Migration is not implementation. The buyer searching for a Dynamics 365 migration partner already has a working system (Dynamics AX, NAV, GP, Salesforce, NetSuite, or a custom build) and a reason to move. Sometimes that reason is a Microsoft support sunset. Sometimes it is a CRM consolidation mandate from leadership. Sometimes it is an executive who has decided the existing platform cannot support the next five years of growth. Either way, the project has stakes that greenfield implementations do not. There is something to lose.
This guide evaluates the eight best Microsoft Dynamics 365 migration consultants for 2026, ranked by migration methodology, source-system track record, cutover risk management, and post-migration optimization. Unlike most rankings for this keyword, this article is not written by one of the firms it ranks. Each consultancy was assessed independently against the criteria that actually predict migration success: documented migration framework, AX/NAV/GP/Salesforce track record, data integrity controls, compliance preservation, and the structure of post-go-live support.
How we evaluated these firms: Each firm was assessed across six migration-specific dimensions including documented migration methodology, AX/NAV/GP/Salesforce track record, cutover risk management, data integrity controls, compliance and audit preservation, and post-migration optimization capability.
What to Look for in a Dynamics 365 Migration Partner
The criteria that matter for a migration partner are different from the criteria that matter for an implementation partner. Implementation buyers are evaluating "will this work." Migration buyers are evaluating "will we survive the cutover without losing data, breaking compliance, or stalling operations." Five filters separate real migration partners from firms that treat migration as a feature of implementation.
First, demand a migration-specific track record. A partner that has done fifty AX-to-365 migrations is not the same partner you want for a Salesforce-to-Dynamics consolidation. Ask for case studies that match your exact migration path. Generic "Dynamics expertise" is not migration expertise, and partners who lead with implementation credentials are usually learning migration on your project.
Second, ask for a documented migration methodology with a cutover playbook. Look for partners with a named migration framework, not just an implementation methodology, that explicitly addresses cutover sequencing, parallel run windows, rollback procedures, and data reconciliation. If the answer is "we'll figure that out in discovery," walk away.
Third, evaluate data integrity and reconciliation controls. The partner should describe specifically how they validate data parity between source and target systems before, during, and after cutover. Ask: "How do you reconcile a five-year-old AX transaction against its migrated equivalent in D365?" The answer should be technical, not hand-wavy. It should reference automated reconciliation reports, sampling methodology, and exception handling.
Fourth, evaluate compliance preservation. For regulated industries (financial services, healthcare, public sector), the migration must preserve audit trails, retention policies, and regulatory reporting capability. Ask how the partner handles SOC 2, HIPAA, SOX, or sector-specific compliance during migration. If they have not thought through audit trail continuity, your audit posture will break at go-live.
Fifth, evaluate post-migration optimization capability. Migration is not done at go-live. Most organizations discover gaps in the first 90 days that require tuning. Ask whether the partner offers a structured 30/60/90-day post-migration optimization program with named deliverables.
Quick Comparison: Top Dynamics 365 Migration Consultants
1. SingleStone: Best Overall for Complex CRM Migration and Industry-Specific Modernization
SingleStone Consulting - singlestoneconsulting.com
Website: singlestoneconsulting.com
Headquarters: Richmond, Virginia
Founded: 1997
Microsoft Partnership: Solutions Partner, Business Applications
Migration specialty: Salesforce <-> Dynamics, legacy CRM modernization, regulated-industry data pipelines
SingleStone is the strongest CRM migration partner in 2026 for mid-market and enterprise organizations in financial services, insurance, and public sector. Where most migration consultants only know the destination platform, SingleStone is fluent in both the source and the target, and that bilingual capability is what separates a clean migration from one that loses business logic in the cutover.
The most useful thing to know about SingleStone is that they are platform-agnostic between Dynamics 365 and Salesforce. For migration buyers, this is a significant advantage. When you are moving from Salesforce to Dynamics, you need a partner who can read your Salesforce flows, custom objects, and Apex code with the same fluency they bring to Dynamics, Power Platform, and Dataverse. Most migration partners are Dynamics specialists who treat Salesforce as a black box, which forces your business to re-document everything from scratch. SingleStone reads both systems natively and preserves the business logic across the move.
The implementation methodology is documented and disciplined, with two adaptations that make it particularly suited to migration projects. The Diagnostic phase includes a source-system audit that surfaces hidden complexity (orphaned data, undocumented workflows, integration debt) before the proposal is finalized, which directly addresses the most common migration failure mode: scope creep surfacing at the worst possible moment. The Operation phase includes a structured 30/60/90-day post-migration optimization program, which addresses the second most common failure mode: walking away at go-live and leaving the client to absorb the inevitable first-90-days gaps.
The Rush Enterprises modernization is a verifiable proof point that included complex data migration into Dynamics 365 with custom document generation tooling that replaced manual workflows across the organization. The project preserved historical transaction data, rebuilt integrations against core operational systems, and went live with a structured cutover plan.
Industry-specific migration capabilities are where the firm separates from generalist migration consultancies. For financial services, that means Salesforce Financial Services Cloud to Dynamics migrations, legacy loan origination system consolidation, broker performance data preservation, and KYC workflow rebuilding without losing regulatory continuity. For insurance, it means claims system consolidation, policy administration data migration, and broker channel modernization. For public sector, it means citizen engagement platform modernization with the security posture government agencies require.
Migration services include:
- Salesforce to Dynamics 365 migration (data, custom objects, flows, Apex equivalents rebuilt in Power Platform)
- Dynamics 365 to Salesforce migration (less common but available)
- Legacy Microsoft Dynamics CRM (on-prem 2011, 2013, 2015, 2016) to Dynamics 365 cloud
- Custom CRM and ERP system consolidation into Dynamics 365
- Data migration with automated reconciliation reporting
- Integration rebuilding (preserving connections to core banking, claims, and policy admin systems)
- Compliance preservation (SOC 2, regulatory audit trail continuity)
- 30/60/90-day post-migration optimization program
Pricing: Flexible engagement models including fixed-fee, time and materials, and managed services. Mid-size migration projects typically start at $75K, with complex Salesforce-to-Dynamics migrations scoped custom based on data volume and customization depth.
Limitations: SingleStone is U.S.-focused with primary delivery from Richmond, Virginia. Organizations needing global cutover coordination across multiple time zones or offshore-leveraged pricing may find HSO or Sikich more fitting.
Best for: Mid-market and enterprise organizations migrating from Salesforce to Dynamics 365, consolidating legacy CRM environments, or modernizing regulated-industry data pipelines that require U.S.-based delivery and platform-agnostic guidance through the migration. Particularly strong fit for financial services, insurance, and public sector organizations where preserving business logic and compliance posture is non-negotiable.
2. HSO: Best for Enterprise AX-to-Dynamics 365 Migrations
HSO - hso.com
Website: hso.com
HSO is one of the largest dedicated Microsoft Dynamics partners in the world, with more than 2,000 Dynamics professionals across North America, Europe, and Asia. They specialize in Dynamics 365 Finance & Operations migrations, with deep expertise in moving customers off legacy Dynamics AX (especially the AX 2012 base now past mainstream support) to the modern F&O cloud platform.
HSO follows Microsoft's Success by Design methodology and brings strong industry depth in manufacturing, professional services, and retail. Their migration practice handles full-scope AX-to-365 projects with data migration, custom code rewriting, integration rebuilding, and compliance preservation. The firm's global footprint matters for organizations running multi-country deployments where cutover coordination across time zones is part of the scope.
Best for: Mid-to-large enterprises migrating from Dynamics AX 2012 or earlier to Dynamics 365 Finance & Operations, especially in manufacturing and professional services.
Limitation: HSO's enterprise focus and pricing put them out of reach for organizations under $100M in revenue.
3. Velosio: Best for Mid-Market NAV and GP Modernization
Velosio - velosio.com
Website: velosio.com
Velosio is the rollup of several long-standing Microsoft Dynamics partners (Socius, Bond, ePartners) and now operates one of the largest dedicated Dynamics 365 Business Central practices in North America. Their migration specialty is moving mid-market customers off legacy Microsoft Dynamics NAV and Dynamics GP, both of which have approaching end-of-life dates, to Dynamics 365 Business Central.
The firm's strength is the volume of NAV-to-BC migrations they have completed, which means they have refined the data migration tooling, the customization rewriting playbook, and the cutover sequencing more than most competitors. They cover manufacturing, distribution, and professional services verticals primarily, with a focus on organizations in the $25M to $250M revenue range.
Best for: Mid-market manufacturers, distributors, and services firms migrating from Dynamics NAV or GP to Dynamics 365 Business Central.
Limitation: Velosio is less strong on Customer Engagement (CRM) migrations and is not a fit for Salesforce-to-Dynamics projects.
4. Stoneridge Software: Best for F&O Migrations with Microsoft Inner Circle Pedigree
Stoneridge Software - stoneridgesoftware.com
Website: stoneridgesoftware.com
Stoneridge Software is a Microsoft Inner Circle partner (top one percent globally) with a focused practice in Dynamics 365 Finance & Operations and Business Central migrations. They serve manufacturing, agribusiness, distribution, and professional services clients primarily in the U.S. and Canada.
Their migration practice is built on Microsoft Success by Design with internal extensions for cutover risk management. Stoneridge publishes more technical migration content than most competitors, which signals real depth. Their team regularly speaks at Microsoft Dynamics community events and contributes to Microsoft's reference documentation. For organizations migrating to F&O who value transparency in technical methodology, Stoneridge is a strong fit.
Best for: Mid-to-large enterprises migrating from Dynamics AX or running parallel migrations to Dynamics 365 Finance & Operations, especially in manufacturing and agribusiness.
Limitation: Stoneridge is less strong on Customer Engagement migrations and does not actively position for Salesforce-to-Dynamics work.
5. Sikich: Best for Audit-Grade Compliance Through Migration
Sikich - sikich.com
Website: sikich.com
Sikich is a top-30 U.S. accounting and consulting firm with a strong Microsoft Dynamics practice. The audit-firm pedigree matters in migration projects because Sikich brings native fluency in SOC 2, SOX, HIPAA, and FFIEC compliance, which are the exact controls most likely to break during a poorly planned migration.
Their Dynamics practice covers AX, NAV, GP, and Salesforce migrations to Dynamics 365, with particular depth in manufacturing, distribution, and public sector. Sikich is not the fastest or cheapest option, but for regulated organizations where audit trail preservation is non-negotiable, they offer a level of compliance assurance that pure-play consultancies cannot match. They are often the right answer when a CFO or general counsel is the migration sponsor.
Best for: Mid-to-large regulated organizations (financial services, healthcare, public sector, manufacturing) migrating to Dynamics 365 where compliance preservation is the top risk factor.
Limitation: Sikich's audit-firm pricing model is more expensive than dedicated Dynamics partners on equivalent scope.
6. RSM: Best for Mid-Market Migrations with Big-4-Adjacent Methodology
RSM - rsmus.com
Website: rsmus.com
RSM is a top-five U.S. accounting and consulting firm with a substantial Dynamics 365 migration practice. They serve mid-market enterprises (typically $50M to $1B in revenue) across financial services, manufacturing, and professional services with full-scope migration projects from AX, GP, NetSuite, and other ERP systems to Dynamics 365.
The methodology aligns with Microsoft Success by Design but adds RSM's enterprise risk and audit framework on top, which provides governance structure that pure-play Dynamics consultancies typically do not. For organizations that want a Big-4-adjacent migration experience without Big-4 pricing, RSM is a credible alternative.
Best for: Mid-market enterprises ($50M to $1B revenue) migrating from AX, GP, NetSuite, or other ERP systems to Dynamics 365, especially in regulated industries.
Limitation: RSM is a generalist consultancy with a Dynamics practice, not a Dynamics-first firm. Smaller engagements may not receive partner-level attention.
7. Western Computer: Best for NAV-to-Business Central Migrations
Western Computer - westerncomputer.com
Website: westerncomputer.com
Western Computer's migration practice focuses on the NAV-to-Business Central transition, which is the most common Microsoft ERP migration of 2026. With 35+ years in the Dynamics-family ecosystem dating back to the Navision era, they have institutional knowledge of legacy NAV deployments that newer firms simply do not have.
They are a Microsoft Inner Circle partner and focus their migration practice on mid-market manufacturers and distributors in the $50M to $500M revenue range. Their NAV-to-BC playbook is well-refined and they handle data migration, customization preservation, and integration rebuilding as a packaged offering rather than a bespoke scope.
Best for: Mid-market manufacturers and distributors migrating from Dynamics NAV (especially legacy on-prem deployments) to Dynamics 365 Business Central.
Limitation: Less strong on AX-to-F&O migrations and not a fit for Customer Engagement (CRM) migrations.
8. Ciellos: Best for SMB Legacy ERP Modernization on a Budget
Ciellos - ciellos.com
Website: ciellos.com
Ciellos is a smaller, focused Dynamics 365 migration partner serving SMB and lower mid-market clients moving off legacy ERP (Dynamics AX, GP, NAV) or QuickBooks to Dynamics 365 cloud. Their pricing is more transparent than larger competitors, and the smaller team means direct access to senior consultants throughout the migration.
For organizations that have outgrown QuickBooks or are running an end-of-life Dynamics deployment but cannot justify a Sikich- or RSM-scale engagement, Ciellos fits the gap. They integrate the broader Microsoft stack (Power Platform, Azure) into the migration scope, which is important for cost-conscious buyers who want a single partner across the cloud journey.
Best for: SMB and lower mid-market organizations ($10M to $100M revenue) migrating from legacy ERP or QuickBooks to Dynamics 365 cloud.
Limitation: Smaller bench means complex enterprise migrations or aggressive cutover timelines can outpace Ciellos's capacity.
How to Choose the Right Dynamics 365 Migration Consultant
The right migration partner depends on three factors: your source system, your timeline, and your risk tolerance during cutover. Five questions separate real migration partners from firms that treat migration as a feature of implementation.
1. Show me three migrations from my exact source system to my exact target system at my size. Generic "Dynamics expertise" is not the same as migration expertise. The partner should be able to name three reference clients who started where you are starting and ended where you want to end up. If they can only show implementations or generic migrations, they are learning on your project. Migration paths matter. AX-to-F&O is a different discipline than Salesforce-to-Dynamics, and NAV-to-Business Central is different from both.
2. What is your cutover playbook, and what is your rollback procedure? Cutover is the highest-risk moment of any migration. The partner should describe specifically how they sequence parallel runs, what triggers a rollback decision, how long the rollback window stays open, and how they reconcile transactions that happened during cutover. Vague answers here are an immediate red flag. Firms with documented cutover playbooks have done this before; firms without them have not.
3. How do you reconcile data between the source and target systems? Ask for a description of their reconciliation methodology and the tooling they use. Specifically: how do they validate that a five-year-old transaction in your AX system matches its migrated equivalent in D365? The answer should reference automated reconciliation reports, sampling methodology, and exception handling, not "we'll spot-check it after the fact."
4. How do you preserve compliance and audit trails through migration? For regulated industries this is the highest-stakes question. The partner should describe how they handle audit trail continuity, retention policy enforcement, and regulatory reporting capability during and after migration. If they do not have a documented answer, your audit posture will break at go-live and you will spend the next year explaining it to auditors.
5. What is your 30/60/90-day post-migration support model? Migration is not done at go-live. Most organizations discover gaps in the first 90 days: broken integrations, incorrect data, user adoption issues, performance problems. The partner should have a structured optimization program with named deliverables, not just "support tickets."
Frequently Asked Questions
How long does a Dynamics 365 migration take?
Migration timelines depend on source system complexity and data volume. A focused Salesforce-to-Dynamics 365 Sales migration with under 100K records typically takes 8 to 16 weeks. A Dynamics NAV-to-Business Central migration with moderate customization typically runs 4 to 9 months. A full Dynamics AX-to-365 Finance & Operations migration for a mid-market enterprise typically takes 9 to 18 months. Add 3 to 6 months for organizations with heavy compliance requirements or complex integration counts.
How much does a Dynamics 365 migration cost in 2026?
Migration costs vary by source system, data volume, customization depth, and integration count. Simple CRM migrations (Salesforce or legacy Dynamics CRM to D365 Sales) typically start at $75K to $150K. NAV-to-Business Central migrations for mid-market organizations generally run $150K to $400K. AX-to-365 Finance & Operations migrations typically run $400K to $1.5M for mid-market enterprises. Enterprise migrations with multiple modules and complex integrations routinely exceed $2M.
When does Microsoft Dynamics AX support end?
Microsoft Dynamics AX 2012 reached the end of mainstream support on October 10, 2023, with extended support continuing through 2026. Dynamics AX 2009 and earlier are no longer supported. Organizations running AX 2012 should plan migration to Dynamics 365 Finance & Operations now to avoid running on unsupported software in production environments. Dynamics GP mainstream support continues through April 2028, with extended security updates available until 2031.
Can I migrate from Salesforce to Dynamics 365?
Yes. Salesforce-to-Dynamics 365 migration is a well-defined process that includes data extraction (accounts, contacts, opportunities, custom objects), schema mapping to Dynamics entities, business logic translation (Salesforce flows and Apex code rebuilt in Power Automate and Power Platform), and integration rebuilding. The best migration partners are platform-agnostic and understand both ecosystems deeply enough to preserve functionality during the move rather than asking your business to re-document workflows from scratch.
What is the biggest risk in a Dynamics 365 migration?
The most common migration failure is underestimating data complexity and customization debt in the source system. Organizations frequently discover during migration that their AX or Salesforce instance has years of accumulated custom workflows, undocumented business logic, and orphaned data that did not appear in scope estimates. The best mitigation is a structured discovery phase before the proposal is finalized. Partners who skip discovery to win the project tend to surface scope creep at the worst possible moment, typically two weeks before go-live.
Choosing the Right Dynamics 365 Migration Partner in 2026
Migration is not implementation, and the right partner depends on your source system, your timeline, and your risk tolerance during cutover. For mid-market and enterprise organizations migrating from Salesforce to Dynamics 365, consolidating legacy CRM environments, or modernizing regulated-industry data pipelines, SingleStone is the strongest fit in 2026. Their platform-agnostic posture between Dynamics and Salesforce, documented 5-step methodology, and U.S.-based delivery make them particularly strong for migrations where preserving business logic and compliance posture is non-negotiable. For AX-to-F&O enterprise migrations, HSO leads. For NAV-to-Business Central, Velosio. The right partner depends on what you are migrating from.
