# Best Data Migration Services: Top US Service Providers in 2026 Ten US data migration firms reviewed for cloud and database migration track record, Clutch ratings, partner tiers, and disclosed hourly rates, ranked for 2026 buyers with an active migration budget, led by LatentView Analytics's multi-platform migration tooling. Comparing the best Data Migration Services of 2026 includes 1. LatentView Analytics 2. Hakkoda, an IBM Company 3. ClearScale 4. phData 5. Mission Cloud Services, a CDW company 6. Resultant 7. Trianz 8. Datavail 9. Rackspace Technology 10. Slalom. Ten US data migration firms reviewed against real project scopes, from a $1,000 Clutch-listed minimum to a $1M-plus Fortune 500 multi-cloud program. We pulled every Clutch profile directly on October 17, 2026, cross-referenced AWS, Azure, Google Cloud, Snowflake, and Databricks partner directories, and read the public case studies that name an actual client or disclose a measurable migration outcome. Where a firm shows zero or thin Clutch reviews, we say so plainly instead of borrowing a number from somewhere else. ## Quick summary - Best overall: LatentView Analytics, the only firm in this guide running a named proprietary AI migration tool, MigrateMate, with a documented Fortune 500 retailer case study and simultaneous AWS, Azure, Snowflake, and Databricks partner status. - Best for Snowflake-native enterprise migrations: Hakkoda, an IBM Company, two consecutive Snowflake Healthcare and Life Sciences Partner of the Year wins and an AI-accelerated migration tool that cuts manual code conversion time. - Best for AWS-only migrations: ClearScale, AWS Premier Tier partner since 2011 with a documented 50% cost cut on a full platform migration. - Best Snowflake boutique: phData, six consecutive Snowflake Americas Partner of the Year wins and near-shore Uruguay delivery on US hours. - Best for mid-market AWS workloads: Mission Cloud Services, a CDW company, named clients including the Boston Celtics and a documented 10x processing capacity gain. ## How we chose We pulled Clutch profiles directly on October 17, 2026 and recorded ratings exactly as shown, including the firms with zero or thin reviews. We cross-referenced the AWS Partner Network directory, Microsoft's Azure partner directory, and Snowflake's and Databricks's partner pages on the same date. Named client outcomes came from each firm's own public case study library, not from a secondary aggregator. Ten of the eleven firms we researched this week cleared the US-headquarters bar; firms with primary delivery outside the US were cut regardless of award history. ## How we weight data migration services for the Topickz score Every tool is scored against this rubric and combined using these category-specific weights into the Topickz score. | Criterion | Weight | What we checked | |---|---|---| | Cloud or database platform partner tier | 20% | We checked AWS, Azure, Google Cloud, and Snowflake partner directories directly and recorded the exact tier. A Premier or Elite tier earns privileged escalation access that a Select or Registered tier does not. | | Named migration track record | 16% | Case studies had to name an actual client and a measurable outcome, a workload count, a cost reduction, or a downtime window, pulled from each firm's own case study library. | | Zero-downtime or low-downtime delivery methodology | 14% | Migrations live or die on cutover night. We looked for documented methodology around data validation, reconciliation, and rollback planning, not just a migration-complete announcement. | | US delivery and data residency | 14% | Each firm had to be US-headquartered with substantial US-based senior delivery. Firms that could not confirm US-only data handling in writing lost points here. | | Clutch rating and review depth | 12% | We pulled Clutch profiles live. Where review counts were thin, 1 to 5 reviews, we flagged it rather than treat it as equivalent to a 50-review firm. | | Hourly rate and minimum-project transparency | 12% | Firms that disclose hourly rate bands and project minimums on Clutch let a buyer build a real budget before the first discovery call. Undisclosed pricing cost points here. | | Industry vertical fit | 12% | A firm strong in healthcare data migration is not automatically the right call for a retail POS cutover. We noted where each firm has real, named depth. | ## Tools compared ### LatentView Analytics: Best overall, proprietary AI migration tooling with simultaneous AWS, Azure, Snowflake, and Databricks partner status **Best overall** Score: 9.2/10 Rating: 4.5/5 (Clutch · 2 reviews) **Starting price:** $1,000+ We are putting LatentView at the top of this list for a reason none of the other nine firms can match: it is the only shop here running a named, proprietary AI migration tool across more than one platform combination. MigrateMate is the differentiator. [The beverage technology provider case study](https://www.latentview.com/case-studies/transforming-enterprise-analytics-migrating-from-snowflake-to-databricks-for-a-leading-beverage-technology-provider/) documents a 1,400-plus table, 24TB Snowflake-to-Databricks migration finished in 30 days. [A separate blog post](https://www.latentview.com/blog/migrating-5000-dbt-models-snowflake-to-databricks/) documents 5,000-plus dbt models moved for a construction management SaaS client. [The US-based shopping channel case study](https://www.latentview.com/case-studies/fast-tracking-cloud-migration/) is the most dollar-specific migration outcome in this entire guide. A Fortune 500 retailer compressed a 2-year migration plan into 6 months, finished 2 months early, and credits over $1M in annual savings. We want to be direct about the gap. [Snowflake's partner directory](https://www.snowflake.com/en/why-snowflake/partners/all-partners/) lists LatentView at Select tier, while [a LatentView press release claims Premier status](https://www.latentview.com/press-release/latentview-analytics-achieves-premier-services-partner-status-with-snowflake/). We could not reconcile the two, so confirm the current tier directly. The firm also holds [AWS Select Tier status](https://www.research-live.com/article/news/latentview-becomes-advanced-consulting-partner-of-amazon-web-services/id/4011459) and a Microsoft Azure Silver partnership. We found no named AWS- or Azure-specific migration case study with a disclosed dollar figure the way the Snowflake-to-Databricks work is documented. If your migration is specifically Snowflake-to-Databricks, this is the clearest first call in the guide. If it is a straight AWS or Azure lift-and-shift, treat the platform breadth as a credential to verify in discovery, not a replacement for ClearScale's or Mission Cloud's AWS-specific depth. **Pros:** - Founded 2006 with a US corporate entity headquartered in Princeton, New Jersey (LatentView Analytics Corporation); the only firm in this guide holding AWS, Microsoft Azure, Snowflake, and Databricks partner status at once rather than specializing in one platform - MigrateMate, LatentView's own AI-powered migration tool, anchors two named, documented client migrations: a beverage technology provider moving 1,400-plus tables, 550-plus dbt models, and 24TB of data from Snowflake to Databricks in a 30-day window, and a construction management SaaS company migrating 5,000-plus daily dbt models off a fragmented stack - Named case study for a US-based shopping channel documents a cloud migration timeline compressed from a planned 2 years down to 6 months, finishing 2 months early, to beat a legacy renewal deadline, with the client crediting over $1M in annual savings **Cons:** - Only 2 Clutch reviews on file at 4.5/5; that is thinner third-party proof than Resultant or Mission Cloud carry, and the Snowflake-to-Databricks case studies read as vendor-published marketing material without independent client confirmation - Snowflake's own partner directory lists LatentView at Select tier while a LatentView press release separately claims Premier Services Partner status; verify the current tier directly before assuming the higher claim, the same discrepancy we flag on their data-warehousing listing - The named shopping-channel case study does not disclose whether the destination cloud was AWS or Azure, and no AWS- or Azure-specific named migration with a dollar figure surfaced in our research the way the Snowflake-to-Databricks work did; this firm's strongest, most specific evidence is Snowflake-to-Databricks migration, not a generic multi-cloud lift-and-shift Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Migration readiness assessment | $10K-$30K (est.) | Legacy platform audit and MigrateMate-scoped migration plan | | Fixed-bid pilot | $50K-$150K (est.) | 30-60 day Snowflake-to-Databricks or dbt-layer migration pilot | | Phase 1 build | $200K-$600K (est.) | 4-6 month full-platform migration plus post-migration optimization | | Managed engagement | $40K-$110K/mo (est.) | Dedicated embedded team for a multi-quarter migration program | ### Hakkoda, an IBM Company: Best for Snowflake-native enterprise migrations, two-time Snowflake Healthcare Partner of the Year with AI-accelerated migration tooling **Best Snowflake enterprise pick** Score: 9.0/10 **Starting price:** $100,000+ Hakkoda is the clearest first call when the migration destination is Snowflake, particularly in healthcare or life sciences. [The two consecutive Snowflake Healthcare and Life Sciences Partner of the Year awards](https://hakkoda.io/resources/snowflake-partner-of-the-year-2025/) are vertical-specific recognition, not a generic tier badge. [Snowflake's own migration-accelerated-partners page lists Hakkoda](https://www.snowflake.com/en/migrate-to-the-cloud/migration-accelerated-partners/hakkoda/) in its top tier, and the [free SnowConvert tool Snowflake now ships](https://www.snowflake.com/en/blog/free-snowconvert-migrations/) is the same accelerator Hakkoda builds its migration practice around. The [CarMax case study](https://hakkoda.io/?p=20323) names an actual client and timeline, a 7-month Teradata-to-Snowflake migration with 4 engineers, which is more specific than most firms in this guide publish. Zero Clutch reviews is the honest gap. The [IBM acquisition announcement](https://newsroom.ibm.com/2025-04-07-ibm-acquires-hakkoda-inc-,-expanding-data-expertise-to-fuel-clients-ai-transformations) adds enterprise contracting weight that regulated buyers will want, at the cost of dealing with IBM procurement instead of a boutique sales process. **Pros:** - Two consecutive Snowflake Healthcare and Life Sciences Data Cloud Services Partner of the Year awards (2024 and 2025); Snowflake Elite SI and MSP status, which is the tier that carries the fastest escalation path for a stuck migration - SnowConvert, now offered free by Snowflake, automates legacy code conversion; a documented Hakkoda customer quote puts the time savings at 10% to 70% depending on code complexity, and Hakkoda's own marketing cites up to 10x faster migrations on top of that base tool - Named client CarMax ran a Teradata-to-Snowflake migration documented over a 7-month project with 4 full-time data engineers; IBM acquisition in April 2025 added enterprise legal, security, and vendor-management infrastructure that regulated buyers require before signing a multi-year MSA **Cons:** - Zero Clutch reviews as of October 2026; procurement teams that lean on Clutch for vendor qualification will need to request references directly from the IBM account team - Procurement now runs through IBM Consulting contracts since the April 2025 acquisition; buyers who want direct access to the original Hakkoda delivery team need to structure that into the SOW during the IBM master agreement negotiation - Primary platform is Snowflake; if your target platform is Databricks or a raw AWS/Azure lift-and-shift with no Snowflake destination, this is not the right first call Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Migration readiness assessment | $15K-$30K | Legacy platform audit and Snowflake target-state design | | Fixed-bid migration | $100K-$300K | 90-120 day Teradata, Oracle, or Redshift to Snowflake migration | | Phase 1 lakehouse build | $300K-$1M | 5-8 month migration plus platform modernization | | Managed Snowflake MSP | $50K-$120K/mo | Post-migration administration, FinOps, and optimization | ### ClearScale: Best for AWS-only migrations, AWS Premier Tier partner since 2011 **Best for AWS** Score: 8.9/10 Rating: 5.0/5 (Clutch · 1 reviews) **Starting price:** $200,000-$999,999 ClearScale is the firm to call when the destination is unambiguously AWS. [AWS Premier Tier status](https://clearscale.com/) is their anchor credential, and it has held since 2011, which is longer than most AWS-specialist shops in this guide have existed. The [btwb case study](https://clearscale.com/empowering-a-global-fitness-platform-to-reduce-costs-byhalf-with-aws/) is the strongest documented outcome in this category: a named client, a 50% cost cut, and a 99.99% availability number post-migration, not a vague satisfaction claim. The [Jonas Fitness case study](https://www.casestudies.com/company/clearscale/case-study/jonas-fitness-prepares-for-thousands-of-databases-and-clients-with-clearscale) shows the phased-prep approach that limits risk on cutover night, which is the part of a migration project that actually goes wrong. One Clutch review is the honest gap here; get three references in your vertical before signing anything above $200K. **Pros:** - AWS Premier Tier Services Partner, the highest consulting tier AWS grants, held consistently since founding in 2011 out of San Francisco; AWS validation specifically covers complex migration project experience, not just general cloud consulting - Named client case study on btwb (Beyond the Whiteboard) documents a full platform migration off a PaaS host onto AWS with near-zero downtime, 50% cost reduction, and 99.99% availability post-migration - Jonas Fitness case study documents a large-scale preparation phase for thousands of databases and client environments ahead of a staged AWS cutover, the kind of phased approach that limits blast radius on cutover night **Cons:** - Only 1 Clutch review on file, even at 5.0/5 that is too thin a sample for an enterprise procurement committee to rely on without direct reference calls - Conflicting team-size data between Clutch sections, 50-249 in one listing and 76-100 in another, worth confirming current headcount directly before assuming bench depth for a large concurrent program - AWS-only specialist; if your migration target is Azure, Google Cloud, or Snowflake, ClearScale is not the right first call despite the strong AWS track record Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Migration evaluator workshop | $10K-$20K | AWS Migration Evaluator business case and TCO modeling | | Fixed-bid pilot | $50K-$150K | 60-90 day pilot migration of 1-2 critical workloads | | Phase 1 platform migration | $200K-$600K | 4-6 month full platform migration to AWS | | Managed post-migration support | $30K-$80K/mo | Ongoing AWS management, cost optimization, and incident response | ### phData: Best Snowflake migration boutique, six consecutive Snowflake Americas Partner of the Year **Best Snowflake specialist** Score: 8.8/10 **Starting price:** $50,000+ phData is the clearest Snowflake-migration call for teams moving off a legacy warehouse or Teradata-style platform. The [six consecutive Snowflake Americas Partner of the Year wins](https://www.phdata.io/blog/phdata-awarded-snowflake-2025-partner-of-the-year/) are not a marketing claim; Snowflake's own partner directory lists them Elite. The [mortgage lender case study](https://www.phdata.io/case-studies) is a genuinely useful data point: 6 source systems consolidated into one pipeline for a $60B loan-volume client. The near-shore Uruguay delivery model is a real differentiator on migration cutover timing specifically, since cutover windows depend on same-day feedback loops that a 12-hour-offset offshore team cannot match. Zero Clutch reviews is the honest gap, and the December 2024 Gryphon acquisition is worth a question on your discovery call about team retention. **Pros:** - Snowflake Elite partner and six consecutive Snowflake Americas Partner of the Year (2020-2025); near-shore delivery model with Uruguay engineers on US hours cuts the 24-hour feedback-loop lag that kills offshore migration cutover windows - Mortgage lender case study documents a migration consolidating 6 disparate source systems into a single Snowflake-plus-Azure Data Factory pipeline for a $60B loan-volume client, giving them their first near-real-time data view post-migration - Regional bank pilot migration completed in 5 weeks, a concrete timeline data point that most firms in this category will not commit to in writing before a signed SOW **Cons:** - Zero verified Clutch reviews as of October 2026; procurement committees requiring third-party social proof will need to request references directly - Acquired by Gryphon Investors in December 2024; standard PE-ownership integration risk applies to multi-year post-migration managed engagements - Snowflake is the primary destination; shops migrating into Databricks Unity Catalog or a raw AWS/Azure data lake with no Snowflake layer should look elsewhere first Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Migration readiness assessment | $5K-$15K | 1-2 week architecture and source-system audit | | Fixed-bid pilot migration | $50K-$150K | 60-90 day pilot migration proof of concept | | Phase 1 full migration | $200K-$600K | 4-6 month warehouse-to-Snowflake migration | | Managed engagement | $60K-$130K/mo | Dedicated team for multi-system, multi-quarter migration | ### Mission Cloud Services, a CDW company: Best for mid-market AWS workload migration, named clients include the Boston Celtics **Best mid-market AWS** Score: 8.6/10 Rating: 4.7/5 (Clutch · 5 reviews) **Starting price:** $10,000+ Mission Cloud is the firm that keeps showing up on mid-market AWS migration shortlists specifically because of disclosed pricing and named outcomes. [Clutch lists Mission at 4.7/5 across 5 reviews](https://clutch.co/profile/mission-cloud), with a $10,000 project minimum and $200-$300/hr, which gives a buyer a real number before the first call. The [Examity migration case study](https://www.missioncloud.com/blog/3-cloud-migration-success-stories-to-motivate-your-migration) documents a 30% cost reduction versus hiring internally, and the [Lexbe case study](https://www.casestudies.com/company/mission-cloud-services/case-study/lexbe-increases-processing-capacity-10x-with-mission-cloud-services) reports a 10x processing capacity gain tied to AWS Migration Acceleration Program funding Mission secured for the client. The Boston Celtics engagement is a recognizable named client, even without published outcome numbers. Five Clutch reviews is a thin sample; verify current rates and request two references before signing above $100K. **Pros:** - AWS Premier Tier Services Partner holding the AWS Migrations Competency; Mission says it has moved thousands of workloads under the AWS Migration Acceleration Program, a claim backed by AWS Marketplace listing status rather than a third-party audit - Named clients include the Boston Celtics, ATCC, Erin Condren, Kanopy, and Runkeeper; the Examity case study documents a 30% reduction in design, build, and implementation cost compared to hiring 4-5 internal engineers for the same migration - Lexbe case study reports a 10x increase in processing capacity after Mission secured AWS Migration Acceleration Program funding and moved the client to a microservices architecture **Cons:** - 4.7/5 across only 5 Clutch reviews, at $200-$300/hr which is a premium rate band for a mid-market AWS specialist; confirm current rate directly since Clutch pricing lags real quotes - Acquired by CDW in recent years; the account-team and procurement process now runs through a much larger parent company, which can mean slower contract turnaround than a true boutique - Beverly Hills HQ with limited documented presence in the Midwest or Northeast; confirm travel and on-site availability before assuming East Coast coverage Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Migration assessment | Free-$10K | AWS workload audit and migration business case | | Fixed-bid pilot | $30K-$80K | 30-60 day pilot migration of 1-3 applications | | Phase 1 workload migration | $80K-$250K | 3-5 month multi-workload AWS migration | | Managed AWS support | $15K-$50K/mo | Post-migration management and cost optimization | ### Resultant: Best for regulated and public-sector cloud migrations, Clutch 4.7/5 with disclosed rates **Best for regulated industries** Score: 8.5/10 Rating: 4.7/5 (Clutch · 8 reviews) **Starting price:** $5,000+ Resultant is the strongest combination of verified Clutch rating and disclosed pricing in this guide, which matters when a procurement committee needs a real number before scoping. [The 8 Clutch reviews at 4.7/5](https://clutch.co/profile/resultant) at $150-$199/hr give a buyer an actual anchor, something most of the firms on this list will not publish. [Google Cloud named them US State and Local Government Partner of the Year](https://resultant.com/blog/company-news/google-cloud-public-sector-partner-of-the-year-2023/), which requires documented delivery outcomes, not just a sales relationship. The [Indiana Pivot workforce platform](https://resultant.com/insights/client-stories/) is a real public-sector data modernization outcome. The 2022 Teknion acquisition broadened their database migration bench into Snowflake and Tableau. For fintech, healthcare, or government migrations on GCP or Snowflake, Resultant is the clearest first call with a real rate card. **Pros:** - 4.7/5 across 8 verified Clutch reviews at $150-$199/hr; the most verified Clutch rating with disclosed hourly rates of any firm in this guide, which gives procurement a real starting number most migration firms will not publish - Google Cloud US State and Local Government Partner of the Year 2023 with runner-up recognition in 2022; built Indiana's Pivot AI workforce recommendation engine, a documented public-sector data migration and modernization project - Teknion Data Solutions acquisition in 2022 added Snowflake, Tableau, and WhereScape expertise, which broadened Resultant past its GCP-only heritage into multi-stack database and warehouse migrations **Cons:** - Indianapolis HQ with limited coastal presence; companies on the West Coast or Northeast will pay travel premiums for on-site cutover phases, proportionally significant on a $5K-$50K engagement - Google Cloud heritage means AWS and Azure senior migration architects are thinner on the bench; verify lead architect experience on non-GCP source platforms before signing if your migration target is Azure or AWS - Broad 250-999 employee portfolio across IT managed services, cybersecurity, and app development; the migration practice competes internally for senior staff time with other service lines Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Migration readiness assessment | $5K-$15K | Cloud migration readiness or legacy database audit | | Fixed-bid pilot | $50K-$150K | 60-90 day pilot migration proof of concept | | Phase 1 build | $200K-$500K | 4-6 month production migration in a regulated vertical | | Managed engagement | $50K-$100K/mo | Ongoing data ops for public sector or healthcare clients | ### Trianz: Best enterprise multi-cloud migration SI, AWS Premier Tier with proprietary migration tooling **Best enterprise multi-cloud** Score: 8.4/10 Rating: 5.0/5 (Clutch · 2 reviews) **Starting price:** $50,000+ Trianz is the right call for an enterprise buyer who needs real bench depth across AWS, Azure, and GCP simultaneously. [AWS Premier Tier status](https://trianz.com/press/trianz-achieves-aws-premier-tier-status) puts them in the same partner bracket as ClearScale and Mission Cloud, at a much larger scale. The [Fortune 500 medical technologies case study](https://www.trianz.com/experiences/cloud-migration-for-a-fortune-500-medical-technologies-and-services-company) documents a 4,000-workload carve-out migration with specific percentage outcomes, 50% faster, 40% cheaper, which is the kind of number a CFO actually reads. The Concierto Migrate tooling and the documented 120-day pilot and 24-week government transformation models give a buyer a predictable engagement shape. Two Clutch reviews and anonymized case studies are the honest gaps; for a program above $500K, request three named references before signing. **Pros:** - AWS Premier Tier Services Partner; founded 2001 in Santa Clara with a 1,000-9,999 employee band, which gives genuine concurrent-engineer capacity most boutiques in this guide cannot match - Documented Fortune 500 medical technologies case study: a 4,000-workload migration off a parent company's Azure tenant onto a standalone AWS environment, reporting 50% faster migration, 40% cost reduction, and a 15% total cost of ownership drop - Concierto Migrate proprietary tooling automates assessment and pilot migration; a 120-day financial services pilot and a 24-week government data center transformation are both documented, structured engagement models with defined scope checkpoints **Cons:** - Only 2 Clutch reviews on file, even at 5.0/5; a sample this small does not substitute for direct reference calls on an enterprise-scale engagement - Published case studies are anonymized by industry and size rather than named, which is a transparency gap next to ClearScale or Mission Cloud, who name actual clients - Hourly rate of $150-$199/hr on Clutch likely understates blended rates on a true enterprise multi-workload program; get a detailed rate card before assuming Clutch pricing holds at scale Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Cloud assessment and pilot | $25K-$60K | 90-120 day automated assessment plus pilot migration | | Fixed-bid migration | $150K-$400K | 4-6 month multi-workload cloud migration | | Enterprise carve-out migration | $500K-$2M | Large-scale divestiture or parent-company data separation | | Managed cloud operations | $60K-$150K/mo | Post-migration multi-cloud operations and FinOps | ### Datavail: Best for database migration and managed DBA, 1,200-plus certified consultants **Best for database migration** Score: 8.3/10 **Starting price:** Quote-only Datavail is the database-migration specialist to call when the problem is specifically Oracle, SQL Server, MySQL, or PostgreSQL, not a cloud platform rebuild. The [Sony DADC migration webinar](https://www.datavail.com/aws-portal-us-west-greenfield/) names an actual enterprise client moving onto SQL Server 2016. A separate [resume case study](https://www.datavail.com/datavail-resume/) documents a 6TB consolidation onto Amazon RDS with a 50% cost cut in licensing, hardware, and data center spend. Their AWS Competency and Service Delivery Partner status is specific to database migration, not general cloud consulting. Zero Clutch reviews on a firm with 1,200-plus consultants is a real gap; this is a case where references matter more than a star rating because the public review footprint simply does not exist yet. **Pros:** - Founded 2007 in Broomfield, Colorado with a 1,000-9,999 employee band and 1,200-plus certified database consultants; genuinely broad Oracle, SQL Server, MySQL, and PostgreSQL migration coverage rather than a single-platform specialty - Named client Sony DADC ran a documented migration onto SQL Server 2016, and a separate case study reports a 50% cut in license, hardware, and data center costs on a 6TB MySQL and SQL Server consolidation into Amazon RDS - Passed AWS requirements for Competency and Service Delivery Partner status specifically in database migration; post-migration managed DBA services mean the handoff does not end the relationship, which matters for teams without in-house DBAs **Cons:** - Zero Clutch reviews as of October 2026; the largest firm by headcount in this guide has the thinnest third-party review footprint, so reference calls are not optional here - Pricing is entirely quote-only with no public rate card or project minimum anywhere, which means your first real budget number comes after a sales conversation, not before - Broad managed-services portfolio across database administration, cloud, and analytics means the migration-specific practice is one line of business among several, not the singular focus a pure migration boutique offers Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Database health check | Free | Initial database assessment and migration scoping call | | Migration strategy and mapping | $15K-$40K (est.) | Data mapping, integrity checks, and migration plan | | Fixed-bid database migration | $50K-$200K (est.) | Single-database or multi-database migration project | | Managed DBA services | $10K-$40K/mo (est.) | Ongoing remote database administration post-migration | ### Rackspace Technology: Most established enterprise cloud and data center migration firm **Most established** Score: 8.0/10 **Starting price:** Quote-only Rackspace Technology is the longest-tenured name in this category, and that tenure shows up in the case studies. The [Housing Authority of the City of Austin migration](https://www.rackspace.com/newsroom/) moved 373 users and 3.7TB onto Azure and Microsoft 365 with documented compliance improvements, a real public-sector outcome. The older [Switchfly case study](https://ir.rackspace.com/node/10591/pdf) is a genuinely large migration, 700 servers and 16TB across 20 client accounts onto Amazon RDS. Rackspace's December 2022 ransomware incident on its Hosted Exchange product is public record and worth asking about directly during due diligence, even though that product line is separate from the migration practice. Zero Clutch reviews on a firm this size and this old means the review gap is structural, not a quality signal; Rackspace simply does not sell through that channel. **Pros:** - Founded 1998 in San Antonio with a 250-999-plus employee band on the data migration practice specifically; 27 years of continuous data center and cloud migration delivery is longer than nearly every other firm in this guide - Housing Authority of the City of Austin case study documents a migration of 373 users and over 3.7TB of data onto Azure and Microsoft 365, improving disaster recovery and supporting government compliance requirements - Switchfly case study documents a larger historical migration, 20 clients, 70 services, 700 servers, and 16TB of data onto Amazon RDS, using Rackspace Optimizer+ to cut post-migration costs **Cons:** - Zero Clutch reviews as of October 2026 despite being one of the largest, longest-running names in this category; Rackspace competes through direct enterprise procurement, not Clutch-driven discovery - Rackspace Technology disclosed a December 2022 ransomware attack on its Hosted Exchange environment that affected customer email access for an extended period; worth a direct question about current security posture and incident-response SLAs before signing - Conflicting employee-count figures across public listings for the specific data migration practice versus the broader company; confirm current team allocation for your account before assuming enterprise-wide headcount applies to your project Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Migration assessment | $20K-$50K (est.) | Data center or cloud migration readiness assessment | | Fixed-bid migration | $100K-$400K (est.) | 3-6 month enterprise workload migration | | Large-scale data center migration | $500K-$2M+ (est.) | Multi-TB, multi-server data center consolidation | | Managed cloud operations | $40K-$150K/mo (est.) | Post-migration managed hosting and operations | ### Slalom: Best established SI for Fortune 1000 cross-platform migration programs **Most established SI** Score: 7.8/10 Rating: 2.0/5 (Clutch · 1 reviews) **Starting price:** $1,000,000+ Slalom is the right call when the migration is one workstream inside a larger Fortune 1000 digital transformation program and your legal team already has an MSA on file. The single Clutch review at 2.0/5 is worth acknowledging directly rather than ignoring. [Gartner Peer Insights submissions for Slalom's data and analytics practice](https://www.gartner.com/reviews/market/business-analytics-services-worldwide/vendor/slalom-consulting) show more nuanced enterprise feedback than the lone Clutch data point. Slalom belongs on the shortlist when the buying committee is a CIO and CFO signing a $5M-plus transformation that includes a migration component, not when it is a data team lead running a standalone 90-day cloud migration. For a pure migration project under $1M, [ClearScale, phData, or Mission Cloud will deliver more migration hours per dollar.](https://clutch.co/us/it-services/cloud-computing) **Pros:** - 13,000-plus consultants across 45 US markets, the only firm in this guide with the bench to run a five-workstream cross-platform migration simultaneously without a resource crunch - AWS Premier plus Azure Gold plus GCP Premier plus Snowflake Premier plus Databricks Premier, the broadest multi-platform partner coverage in this guide under a single MSA, useful when the buying committee wants one prime contractor across source and target - Gartner Peer Insights presence with verified enterprise submissions in Data and Analytics Services; the Gartner record carries more weight than Clutch at the CIO and CFO buying level common on migration programs this size **Cons:** - Clutch profile shows 1 review at 2.0/5, from an IT manager who stated a project never delivered on time and they would not do business with Slalom again; this is the only third-party platform data point publicly available - $1M-plus effective project minimum for a genuine migration program; the Clutch-listed $100-$149/hr rate does not reflect actual blended senior-principal rates once PMO overhead is included - Large-firm overhead is real on migration programs: expect weekly steering committees and formal change-order processes that smaller boutiques in this guide skip entirely Pricing breakdown: | Plan | Price | Best for | |---|---|---| | Discovery and scoping | $50K-$100K | Enterprise migration strategy and current-state assessment | | Phase 1 migration | $500K-$1.5M | 5-8 month enterprise platform migration | | Multi-phase migration program | $2M-$10M+ | 18-36 month multi-system transformation with migration as one workstream | | Managed delivery team | $150K-$400K/mo | 20-50 consultant embedded delivery at enterprise scale | ## More ## Why data migration is its own buying decision Data migration gets bundled into "cloud consulting" or "data engineering" RFPs more often than it should. The problem is specific: moving data, databases, or entire platforms from one system to another without losing integrity or blowing a budget on an extended downtime window. That is a different skill than building a new pipeline from scratch. The ten firms in this guide split into five practical groups, and which one you call first depends on your source and target platform, not which name is biggest. **The firm with its own named migration tooling.** LatentView Analytics built MigrateMate specifically to automate Snowflake-to-Databricks migration, and has two documented client migrations plus a named Fortune 500 cost-savings case study to show for it. We rank it first on that combination, with the honest caveat that its AWS- and Azure-specific migration evidence is thinner than its Snowflake-to-Databricks track record. **Platform-specific migration specialists.** ClearScale (AWS only) and phData (Snowflake-destination) have built their entire practice around one platform's migration tooling and partner escalation path. If your source and target are both clear, these specialists move faster than a generalist will. **Database migration and managed DBA firms.** Datavail is the outlier here, built around Oracle, SQL Server, MySQL, and PostgreSQL migrations rather than a cloud platform move. If your project is a database engine change, not a cloud relocation, this is a different shortlist entirely. **Mid-market AWS and GCP generalists.** Mission Cloud Services and Resultant both disclose Clutch pricing and have named-client case studies at a budget most startups and mid-market companies can actually afford. **Enterprise-scale multi-platform SIs.** Trianz, Rackspace Technology, and Slalom have the bench to run a multi-workstream carve-out or data center consolidation. Below $500K, these three are usually the wrong call on cost-per-hour alone. --- ## What's changing in data migration services in 2026 **AI-accelerated code conversion is becoming table stakes, not a differentiator.** Snowflake made SnowConvert free in 2026, which means the tool Hakkoda built part of its practice around is now available to any firm. The differentiator is shifting from "do you have the tool" to "how many migrations has your team run with it," which favors firms with documented case study volume. **Ransomware and security incidents are now a required due-diligence question, not an edge case.** Rackspace Technology's 2022 Hosted Exchange ransomware attack is the clearest example in this guide. Buyers running regulated-industry migrations should ask every shortlisted firm about current incident-response SLAs before assuming a long operating history equals current security maturity. **AWS Migration Acceleration Program funding is quietly subsidizing mid-market migrations.** Mission Cloud's Lexbe and Examity case studies both reference MAP funding directly. Ask your AWS Premier partner whether your project qualifies before budgeting the full migration cost out of pocket. **Private equity and strategic acquisitions are consolidating the boutique migration market.** phData (Gryphon Investors, December 2024), Hakkoda (IBM, April 2025), and the earlier 2nd Watch (Accenture, 2021) and SADA (Insight Enterprises, 2024) deals all moved independent migration specialists under larger parent companies. Expect the procurement process, not necessarily the delivery team, to change post-acquisition. **Carve-out and divestiture migrations are a growing category of their own.** Trianz's Fortune 500 medical technologies case study, a parent-company data separation under a tight deadline, reflects a growing M&A-driven migration category. If your migration is tied to a divestiture or acquisition, ask firms specifically about carve-out experience, not just general cloud migration volume. --- ## Selection criteria, what to vet before signing an MSA **One, confirm the source-to-target platform match before anything else.** A firm that is excellent at AWS-to-AWS re-architecture may have never touched an Oracle-to-SQL-Server database engine change. Ask for two migrations in the past 18 months with your exact source and target combination. **Two, verify partnership tiers directly from the vendor directory.** Check the [AWS Partner Network directory](https://partners.amazonaws.com/), [Microsoft's partner directory](https://www.microsoft.com/en-us/solution-providers/home), and [Snowflake's partner directory](https://www.snowflake.com/en/why-snowflake/partners/all-partners/) yourself. Firm websites lag real tier changes by 30-90 days. **Three, ask for the rollback and validation plan in writing before signing.** Any firm can describe a migration plan. Ask specifically what happens if cutover fails at 2am, and get the rollback window and data-reconciliation method documented in the SOW, not described verbally. **Four, request named references from the past 18 months, not nominated ones.** Ask for every client in your industry and platform combination from the past year and a half, then pick three yourself. Call them and ask one direct question: would you sign the same SOW again? **Five, price the managed-services tail, not just the migration.** Most migrations need 3-6 months of post-cutover support. Get that rate locked in the same MSA as the migration SOW, not negotiated separately after you have no leverage left. **Six, confirm data residency in writing before the SOW, not during it.** For regulated buyers, ask directly whether any data will touch infrastructure outside the United States during the migration itself, including staging environments, not just the final destination. --- ## Capability matrix at a glance Five migration-specific capabilities across all ten firms, reflecting publicly documented work as of October 2026. | Firm | Assessment & discovery | Zero/low-downtime cutover | Legacy code conversion | Data validation & reconciliation | Post-migration FinOps | |---|---|---|---|---|---| | LatentView | N (shopping channel) | documented (30-day window) | MigrateMate AI | documented | limited | | Hakkoda | Elite | N (CarMax) | SnowConvert AI | documented | via Snowflake Horizon | | ClearScale | AWS Migration Evaluator | N (btwb) | limited | documented | AWS Cost Explorer | | phData | Elite | N (mortgage lender) | limited | documented | Snowflake native | | Mission Cloud | N (Examity) | N (Lexbe) | limited | documented | AWS native | | Resultant | GCP native | M | limited | documented | GCP native | | Trianz | Concierto Migrate | N (medical tech) | limited | documented | multi-cloud | | Datavail | N | documented | SQL conversion | Elite | limited | | Rackspace | N (HACA, Switchfly) | documented | limited | documented | Optimizer+ | | Slalom | Elite | documented | limited | documented | multi-cloud | `N` means a named client case study documents that capability directly. `M` means multiple engagements without a published client name. `Elite` means the firm's own proprietary tooling covers that column. Datavail stands out as the only firm with dedicated SQL-to-SQL code conversion depth, reflecting its database-engine-change specialty rather than a cloud-platform focus. Hakkoda, ClearScale, and LatentView have the clearest named-client proof on cutover execution specifically, with LatentView the only one of the three anchored on its own proprietary migration tool rather than a platform vendor's free tooling. --- ## Industry focus matrix `N` = named clients publicly disclosed in case studies. `M` = multiple engagements, not named publicly. `•` = some documented experience. `✗` = no public evidence found. | Firm | Financial services | Healthcare/life sciences | Retail/CPG | Public sector | Media/entertainment | |---|---|---|---|---|---| | LatentView | • | ✗ | N (shopping channel, beverage tech) | ✗ | N (shopping channel) | | Hakkoda | M | N | • | ✗ | ✗ | | ClearScale | • | • | N | ✗ | N | | phData | N | M | N | • | ✗ | | Mission Cloud | • | • | • | ✗ | N | | Resultant | M | M | • | N | ✗ | | Trianz | N | N | • | N | ✗ | | Datavail | M | N | • | • | N | | Rackspace | M | • | • | N | ✗ | | Slalom | N | N | N | N | • | Trianz and Slalom carry the broadest named-client coverage across verticals. Resultant and Rackspace are the two firms with the clearest public-sector migration track record. ClearScale, Mission Cloud, and LatentView all show up in media, entertainment, or retail, though LatentView's named depth sits narrowly in retail-adjacent and beverage-technology clients rather than across a broad vertical spread. --- ## Tech stack coverage Partnership tiers verified against AWS, Azure, Google Cloud, Snowflake, and Databricks partner directories on October 17, 2026. | Firm | AWS | Azure | Google Cloud | Snowflake | Database engines (Oracle/SQL Server) | |---|---|---|---|---|---| | LatentView | Select | Silver | not listed | Select (firm claims Premier, unverified on directory) | via MigrateMate (Snowflake/Databricks) | | Hakkoda | Select | Select | Select | Elite/MSP | via Snowflake only | | ClearScale | Premier | not listed | not listed | not listed | via AWS RDS/DMS | | phData | Advanced | Select | Select | Elite | via Snowflake migration | | Mission Cloud | Premier | not listed | not listed | not listed | via AWS RDS | | Resultant | Advanced | Select | Premier | Select | via Teknion acquisition | | Trianz | Premier | Gold | Premier | not listed | via Concierto | | Datavail | Competency Partner | Select | not listed | not listed | Elite (Oracle/SQL Server/MySQL/PostgreSQL) | | Rackspace | Premier | Gold | Select | not listed | via managed hosting | | Slalom | Premier | Gold | Premier | Premier | via multi-cloud SI | ClearScale and Mission Cloud are AWS-only by design, which is a strength when the target is unambiguously AWS and a limitation otherwise. Datavail is the only firm with dedicated database-engine Elite-level coverage rather than cloud-platform partner tiers. Slalom holds Premier or Gold across every major platform, the broadest coverage in the guide at enterprise pricing. LatentView is the only firm holding AWS, Azure, and Snowflake status simultaneously at this team size, though its Databricks partnership and Snowflake tier both carry the same directory-versus-press-release discrepancy we flag in its pros and cons. --- ## How to choose the right data migration firm for your team ### 1. Your source and target platform combination AWS-to-AWS or on-prem-to-AWS: ClearScale or Mission Cloud. Legacy warehouse or Teradata to Snowflake: Hakkoda or phData. Snowflake-to-Databricks specifically: LatentView, the only firm here with a named proprietary tool built for that exact move. Database engine changes, Oracle to PostgreSQL or SQL Server consolidation: Datavail. Multi-cloud or GCP-primary: Resultant or Trianz. ### 2. Your project budget Under $100K: LatentView's $1K Clutch-listed minimum, Resultant's $5K minimum, or Mission Cloud's $10K minimum are the realistic entry points. $100K-$500K: ClearScale, phData, Mission Cloud, LatentView, or Trianz. $500K-plus: Trianz, Rackspace, or Slalom have the bench for multi-workstream programs. ### 3. Whether this migration is a carve-out or standalone project Standalone platform migration: any specialist on this list fits. Divestiture, acquisition, or parent-company data separation: Trianz has the most directly documented carve-out experience of any firm here. ### 4. Your tolerance for downtime risk If cutover downtime is unacceptable, ask every shortlisted firm for a written rollback plan before scoping, not after. Hakkoda, ClearScale, and Rackspace all have documented near-zero-downtime case studies to reference directly. ### 5. The weight of US-only delivery phData runs near-shore from Uruguay on US hours; Resultant, Datavail, Mission Cloud, ClearScale, Trianz, and Rackspace all run primarily US-based senior delivery. Hakkoda's team sits inside IBM post-acquisition, which is a mixed but still US-anchored delivery model. LatentView's US contracting entity is headquartered in Princeton, New Jersey, though its publicly listed parent company is headquartered in Chennai, India; confirm which delivery team touches your account if a fully US-based team is a hard requirement. --- ## Engagement model and pricing reality What firms disclose versus what a real first-year migration costs, based on Clutch-disclosed rates and public case study data. | Firm | Clutch hourly rate | Disclosed minimum | Common engagement model | Year-1 all-in reality | |---|---|---|---|---| | LatentView | $150-$199 | $1,000 | Fixed-bid pilot then managed | $75K-$450K (est.) | | Hakkoda | Undisclosed | $100K | Fixed-bid migration or MSP | $300K-$1M | | ClearScale | Undisclosed | $200K-$999K (common size) | Fixed-bid pilot then managed | $200K-$600K | | phData | Undisclosed | $50K | Fixed-bid migration or managed team | $200K-$600K | | Mission Cloud | $200-$300 | $10K | Fixed-bid or T&M | $80K-$250K | | Resultant | $150-$199 | $5K | T&M or fixed-bid | $100K-$500K | | Trianz | $150-$199 | $50K | Fixed-bid then managed | $150K-$2M | | Datavail | Undisclosed | Quote-only | Fixed-bid migration or managed DBA | $50K-$200K | | Rackspace | Undisclosed | Quote-only | Fixed-bid or managed hosting | $100K-$2M+ | | Slalom | $100-$149 | $1M+ effective | T&M or fixed-bid program | $1M-$10M+ | LatentView's disclosed $1,000 minimum on Clutch is a formality that gets a first call booked, not a realistic budget floor for a real migration program; treat it the same way as Resultant's $5,000 figure. The single biggest forecasting error on migration projects specifically: underestimating the post-cutover stabilization period. Nearly every firm in this guide prices a 2-4 week stabilization window separately from the core migration SOW. Ask for that line item up front, not as a surprise change order in week one of go-live. --- ## RFP playbook, from scoping to kickoff Most $200K-plus migration programs run 8-12 weeks from initial scoping to contract signing, shorter than a greenfield build because the scope is more bounded. **Phase 1 (weeks 1-2): Source-and-target scope document and RFI.** Document your current platform, target platform, data volume, and acceptable downtime window. Send to 4-6 firms matched to your platform combination. Down-select to 3 based on relevant migration experience. **Phase 2 (weeks 3-5): Technical scoping call and fixed-bid proposal.** Request a fixed-bid proposal for the pilot migration plus a T&M rate card for the full rollout. Ask each firm to walk through their rollback plan on the call, not just in the written proposal. **Phase 3 (weeks 6-8): Reference checks and SOW negotiation.** Call two named references with your exact platform combination. Negotiate the rollback plan, data residency terms, and post-cutover stabilization window into the MSA before signing. **Phase 4 (weeks 9-12): Pre-cutover rehearsal and kickoff.** Run a dry-run migration in a staging environment before the live cutover date. Confirm the escalation path and who makes the go/no-go call on cutover night before the first billable day. --- ## Final pick by project size and migration type - **Snowflake-to-Databricks migration specifically:** LatentView Analytics, the only firm in this guide with a named proprietary tool, MigrateMate, and two documented client migrations built around that exact move. - **Under $75K, Snowflake destination:** Resultant for GCP-adjacent shops, or a lighter-touch phData or LatentView readiness assessment first. - **$75K-$300K, AWS source or target:** ClearScale or Mission Cloud, both AWS Premier Tier with disclosed or near-disclosed pricing. - **$75K-$300K, Snowflake destination:** phData for the migration itself; Hakkoda if the vertical is healthcare or life sciences specifically. - **Database engine change (Oracle, SQL Server, PostgreSQL, MySQL):** Datavail is the only firm in this guide built specifically around that problem. - **$300K-$1M, multi-cloud or GCP-primary:** Trianz or Resultant, depending on whether the vertical is regulated public sector (Resultant) or enterprise carve-out (Trianz). - **$500K-plus data center consolidation:** Rackspace Technology, with 27 years of continuous delivery in this exact category. - **$1M-plus, cross-platform transformation program with migration as one workstream:** Slalom for buying-committee optics; pair with phData, Hakkoda, or LatentView as platform-specific sub-vendors within the Slalom SOW. - **Carve-out or divestiture migration under a tight regulatory deadline:** Trianz has the most directly documented experience in this specific category. - **Fastest-named, dollar-specific cost outcome in this guide:** LatentView's shopping-channel case study, a 2-year migration compressed to 6 months with over $1M in credited annual savings, though the destination cloud platform is not disclosed in that specific case study. If your shortlist is still two firms after reading this guide, ask both for their written rollback plan for a simulated cutover failure. The firm with the more specific answer, not the more confident one, is usually the better operational fit.

Enterprise SIs like Slalom start near $1M. ### How long does a cloud data migration usually take? A single-workload pilot runs 60-90 days. A full platform migration typically takes 4-8 months depending on data volume. ### What is the biggest risk during a data migration cutover? Downtime and data integrity loss during cutover night. Ask every firm for their rollback and validation plan before signing. ### Should I pick a cloud-specific specialist or a multi-cloud generalist? Specialists like ClearScale or phData move faster on their one platform. Generalists like Trianz or Slalom fit multi-cloud carve-outs. ### What is AWS Premier Tier partner status and why does it matter? It is AWS's top consulting tier, requiring proven migration delivery. Premier partners get faster AWS escalation access. ### How do I budget for post-migration costs? Add 15-20% contingency for change orders plus a managed-services retainer, typically $15K-$100K/month depending on scale. ### Can a small firm handle an enterprise-scale data center migration? Usually not alone. Enterprise carve-outs above $500K typically need Trianz, Rackspace, or Slalom-level bench depth. ### What should I ask for before signing a migration SOW? Named delivery team, data residency terms in writing, a validation and rollback plan, and three references in your industry. ### Is zero downtime migration actually possible? Near-zero is realistic with staged cutover and replication. True zero downtime is rare and usually costs significantly more. ### How do I verify a firm's AWS, Azure, or Snowflake partner tier? Check the AWS, Azure, or Snowflake partner directories directly. Firm websites can lag real tier changes by 30-90 days.
