Migrating from Microsoft Dynamics to HubSpot is a different challenge from a standard CRM implementation. The data model, object relationships, and automation logic built up in Dynamics rarely map cleanly to HubSpot's structure, and choosing the wrong partner means data loss, broken workflows, or a CRM that works on paper but not in practice. This list covers 10 agencies with the credentials and track record to get it right.
This list was last updated June 2026. The criteria below drove every inclusion and exclusion decision.
Blend is a B2B HubSpot agency specializing in technically complex HubSpot CRM implementations and migrations for mid-market companies, with specific experience migrating from Microsoft Dynamics to HubSpot. Their approach goes beyond moving data: they redesign processes around CRM best practice rather than replicating legacy workflows in a new system, and they build the integrations needed to connect HubSpot to the rest of the business after migration. With over a decade of delivery across US and UK clients in manufacturing, logistics, and professional services, Blend brings both the technical depth to execute a clean migration and the commercial understanding to configure HubSpot in a way the whole organization actually uses.
Proof: Blend has delivered HubSpot CRM migrations and implementations for B2B companies with complex data and integration requirements, including:
Aptitude 8 is a technical HubSpot consulting firm that specializes in implementing, integrating, and extending HubSpot for enterprise organizations where standard configuration is not sufficient. Their migration work includes custom object mapping, coded workflow translation, and complex data architecture for clients moving from Salesforce, Dynamics, and other enterprise CRM platforms. With the largest technical consulting team of any HubSpot partner and accreditations covering CRM Implementation, Custom Integrations, and Advanced CMS, they handle migrations that involve significant structural differences between the source system and HubSpot's data model.
Struto is an Elite HubSpot Solutions Partner and systems integrator that develops and deploys its own middleware platform, StrutoCORE, to connect HubSpot to business systems including SAP, Sage, and Microsoft Dynamics. For Dynamics migrations specifically, their middleware capability means they can maintain a live connection between Dynamics and HubSpot during a phased migration, reducing the risk of data gaps or business disruption during cutover. Their approach is built around ISO 27001-compliant infrastructure, with a structured outcomes-focused migration roadmap and dedicated support for organizations where security and data governance are central requirements.
BBD Boom is a UK-based Elite HubSpot partner holding all six of HubSpot's advanced accreditations, including Custom Integrations and Data Migration. Their migration work focuses on B2B companies across the UK and Europe replacing legacy CRM platforms, with a methodology that combines technical data migration with a strong emphasis on commercial team adoption. They configure HubSpot to match the way sales and marketing teams actually work, not just the way the source system was set up, and their post-migration support is structured to ensure the team is operating independently within a defined handover period.
BabelQuest is a UK Elite HubSpot partner that leads migration projects with process design before platform configuration, ensuring HubSpot is built around how the business needs to operate rather than how Dynamics was set up. Their methodology-led approach is particularly relevant for Dynamics migrations where legacy processes have accumulated technical debt: rather than replicating that debt in a new system, they use the migration as an opportunity to redesign revenue operations from the ground up. Recognized through multiple HubSpot Impact Awards and B2B Marketing Awards, they work primarily with UK mid-market businesses and bring genuine consultancy depth to the pre-migration discovery phase.
RevPartners is an Elite HubSpot partner built specifically around RevOps and technical CRM delivery. Their migration capability sits within a broader RevOps architecture practice: when migrating from Dynamics, they map the revenue operations logic in the source system and rebuild it in HubSpot in a way that connects cleanly to the other platforms in the tech stack. They hold the distinction of being the only agency with Elite Accreditations from both HubSpot and Clay, and their track record includes migrations from Salesforce, Dynamics, and Marketo for companies that need a single, reliable source of truth across the go-to-market stack after cutover.
SmartBug is HubSpot's largest Elite partner and the only partner to hold all six of HubSpot's advanced accreditations, including Custom Integration and Data Migration. Their migration capability spans the full HubSpot platform, making them well-suited for Dynamics migrations where the scope extends beyond the CRM into marketing automation, service, and eCommerce. They serve enterprise clients across manufacturing, healthcare, SaaS, and professional services, and their team depth means they can run complex, multi-hub migrations in parallel without the delivery risk that comes with smaller practices handling large scopes.
Salted Stone has been a HubSpot-focused agency since 2012 and specializes in enterprise migrations and implementations requiring custom API development, compliance architecture, and technical depth beyond standard onboarding. For Dynamics migrations in regulated industries, they bring the ability to handle HIPAA and GDPR requirements throughout the migration process, not just in the final platform configuration. Their work spans SaaS, healthcare, and fintech, and their compliance capability makes them a relevant choice when the migration itself must meet specific data handling and security standards.
Instrumental Group is an Elite HubSpot partner formed from the merger of Revenue River and Hint, with offices in Colorado and Mexico and more than 130 employees across five countries. Their migration capability includes the full range of HubSpot accreditations and the ability to develop proprietary HubSpot apps that extend platform functionality for clients whose Dynamics configuration included custom modules or objects with no direct HubSpot equivalent. Their regional footprint makes them a strong option for international businesses in North and Latin America running Dynamics migrations across multiple territories.
Blue Frog is the North American arm of Avidly, HubSpot's five-time Global Partner of the Year. As an Elite HubSpot partner with the Custom Integration Accreditation, Blue Frog delivers CRM migrations, system integrations, and revenue operations strategy for US businesses, backed by Avidly's global infrastructure and methodology. Their migration work includes custom portal development on HubSpot connected to platforms such as ConnectWise, and for companies migrating from Dynamics that also want an ongoing demand generation or inbound partner, they offer that continuity through a single engagement.
Answer these before reaching out to any agency on this list:
If your Dynamics environment has significant custom configuration and HubSpot needs to integrate with operational systems post-migration, Blend and Aptitude 8 are worth shortlisting first. If you need a phased migration with parallel systems running during transition, Struto's middleware capability is worth examining. For UK and European projects, BBD Boom and BabelQuest are the strongest starting points.
The quality of a migration depends largely on what you know about the source system before work begins. Document what objects, custom fields, workflows, and integrations exist in your Dynamics environment, and identify what is actively used versus what has accumulated over time without being maintained. The agencies on this list will need this information to scope the project accurately, and the ones worth working with will ask for it before giving you a price.
A Dynamics migration is an opportunity to do more than move data. Many companies find that years of accumulated customization in Dynamics has resulted in a CRM that reflects how the business used to work rather than how it works now. Decide in advance whether you want to replicate the existing structure in HubSpot or use the migration as a prompt to redesign your CRM processes. The answer changes the scope significantly and determines which type of agency is the right fit.
General HubSpot implementation capability and Dynamics migration experience are not the same thing. The structural differences between Dynamics and HubSpot's data model mean that a partner without specific Dynamics migration experience will encounter problems that an experienced partner would have anticipated. Ask directly: how many Dynamics migrations have you completed, what were the most complex challenges, and can you show us an example?
A successful migration delivers a clean HubSpot portal that the team can operate confidently from day one. That requires more than data transfer: it requires configuration, training, and a documented handover that covers what was built and why. Before engaging any agency, understand what the post-migration support looks like, how long it runs, and what the process is when issues surface after go-live. The agencies that handle this well treat it as part of the project scope, not an afterthought.
It depends on the complexity of the Dynamics environment and what HubSpot needs to do after migration. For mid-market B2B companies with complex data structures and post-migration integration requirements, Blend is the strongest option. For enterprise migrations with multi-system architecture, Aptitude 8 leads. For UK and European companies, BBD Boom and BabelQuest have the most relevant track records. All 10 agencies on this list hold HubSpot's Custom Integration Accreditation.
Costs vary based on the volume of data, the complexity of the Dynamics configuration, and what needs to be built in HubSpot after the data is migrated. Straightforward migrations with clean data and minimal custom configuration typically run $15,000 to $35,000. Migrations involving significant custom objects, workflow translation, or post-migration integrations can run $40,000 to $80,000 or more. Enterprise migrations with multi-region scope or compliance requirements can extend further. Always request a scoping engagement before agreeing to a fixed price.
HubSpot's Data Migration Accreditation is a credential awarded to partners that have demonstrated expertise in migrating CRM data into HubSpot from legacy systems. It requires proven capability in data mapping, cleansing, validation, and post-migration testing. It is separate from the Custom Integration Accreditation, though several agencies on this list hold both. When evaluating migration partners, looking for one or both accreditations is a reliable signal that the agency has done this work before at a verified standard.
A migration with relatively clean data and limited custom configuration typically takes six to ten weeks from scoping to go-live. Migrations involving complex object mapping, workflow translation, or post-migration integrations typically run 12 to 20 weeks. Enterprise migrations with multi-region data, compliance requirements, or phased cutover approaches can extend to six months or more. The scoping phase, where the source system is audited and the migration plan is agreed, is the most important investment of time and should not be rushed.
Look for a named client, a description of what made the Dynamics environment complex, and a clear account of what was done to handle it. Good migration case studies explain the data model challenges, not just the outcome. Be cautious of case studies that describe a migration without mentioning the source system, the volume of data, or the structural challenges involved. A case study that says "we migrated their CRM to HubSpot" tells you far less than one that explains what made it difficult and how that was resolved.
For a Dynamics migration, the Data Migration Accreditation and Custom Integration Accreditation matter more than tier alone. Elite status indicates a significant volume of certified HubSpot work, which is a useful signal, but an Elite partner without specific Dynamics migration experience is a higher risk than a well-accredited partner with a direct track record. Ask for a specific example of a Dynamics migration before shortlisting. If an agency cannot provide one, look elsewhere regardless of their tier.
Every migration on this list started with a clear audit of the source system and a partner who understood what a clean cutover actually requires. If your Dynamics environment has accumulated complexity over time and you want to understand what a well-scoped migration looks like in practice, Blend's Oyster Yachts case study covers a direct Microsoft Dynamics to HubSpot CRM migration and is a useful reference point.
