Upgrading legacy Microsoft Dynamics to the cloud
Many organizations still rely on legacy Microsoft Dynamics ERP systems such as Microsoft Dynamics NAV, Microsoft Dynamics GP, Microsoft Dynamics SL, Microsoft Dynamics AX, and Microsoft Solomon.
As business requirements evolve, these systems can create limitations around scalability, integration, and access to real-time data.
As a result, many organizations are now prioritizing a legacy Microsoft Dynamics upgrade as part of a broader ERP modernization strategy.
Why companies are upgrading legacy Dynamics systems
Organizations pursuing cloud ERP migration are typically looking to:
Move away from on-premises infrastructure
Reduce ongoing maintenance and IT costs
Improve integration with modern business applications
Gain real-time reporting and analytics
Enable automation and AI-driven processes
Upgrading to a modern cloud ERP platform allows businesses to operate more efficiently and scale more effectively.
What is a legacy Microsoft Dynamics ERP system?
The term legacy Microsoft Dynamics ERP typically refers to earlier generations of Microsoft’s enterprise resource planning software that were originally designed for on-premises deployment.
Microsoft Dynamics NAV
Microsoft Dynamics NAV has long been one of Microsoft’s most widely deployed mid-market ERP platforms.
Many organizations running NAV today are exploring a Dynamics NAV upgrade to Business Central as part of their ERP modernization strategy.
Microsoft Dynamics GP
Microsoft Dynamics GP is widely used for financial management and accounting operations.
Organizations running GP often pursue a Dynamics GP upgrade in order to access modern cloud capabilities.
Microsoft Dynamics SL / Solomon
Microsoft Dynamics SL and Microsoft Solomon have historically supported project-driven organizations such as professional services firms.
Many organizations running these systems are now evaluating a Dynamics SL migration to Business Central.
Microsoft Dynamics AX
Microsoft Dynamics AX is an enterprise-grade ERP platform designed for larger organizations.
Many companies running AX are upgrading to the cloud through an AX to Finance and Supply Chain Management migration.
Why organizations are replacing legacy Dynamics ERP systems
Many companies are upgrading legacy Microsoft Dynamics systems because older ERP platforms struggle to support modern business requirements.
Common drivers of legacy ERP modernization include:
Limited cloudcapabilities
Many legacy ERP systems were designed before cloud computing became standard.
Integration limitations
Older systems often struggle to integrate with modern applications such as analytics tools and automation platforms.
Security and complianceconcerns
Maintaining older infrastructure can create security risks and compliance challenges.
Lack of real-timeinsights
Organizations increasingly need real-time data to make better business decisions.

Choosing between Business Central and Finance & Supply Chain Management
Selecting the right cloud ERP platform depends on several factors.
Simple → Business Central
Complex → Finance & SCM
| Number of users | Typical ERP platform |
|---|---|
| Under 300 | Business Central |
| 300–1000 | Depends on complexity |
| 1000+ | Finance & Supply Chain Management |
Business Central

- Longer deployment timelines
Common legacy Dynamics upgrade paths
Most organizations upgrading legacy Microsoft Dynamics systems follow one of several common migration paths.
| Legacy system | Typical upgrade path | Detailed migration guides: |
|---|---|---|
| Dynamics NAV | Business Central | NAV to Business Central |
| Dynamics GP | Business Central | GP to Business Central |
| Dynamics SL | Business Central | SL to Business Central |
| Dynamics AX | Finance & Supply Chain Management | AX to Finance and Supply Chain Management |
Planning an ERP migration strategy
A successful ERP migration strategy requires careful planning and structured execution.
The cost of upgrading to Dynamics 365 varies depending on several factors, including:
- Number of users
- Complexity of the ERP environment
