In today’s fast-paced business environment, staying competitive often hinges on leveraging the latest technology. For organizations using legacy systems like Dynamics NAV or Dynamics AX, the question isn’t whether to modernize but how.
Two primary pathways exist: upgrading or migrating to Microsoft Dynamics 365 Business Central.
While the terms are sometimes used interchangeably, they represent distinct processes with unique implications for cost, complexity, and timelines.
Let’s break down the differences and explore which option aligns with your business goals.
Understanding the Key Differences
1. Upgrade: Evolution Within the Same Ecosystem
An upgrade typically involves moving to a newer version of your existing software. For example, transitioning from Dynamics NAV 2018 to Dynamics 365 Business Central is an upgrade.
This process retains your core database structure, customizations, and historical data, converting them to the new system.
Upgrades are ideal for businesses seeking continuity with minimal disruption, as they preserve workflows while unlocking new features like AI-driven analytics or cloud scalability.
2. Migration: A Strategic Shift to a New Platform
Migration, on the other hand, means moving to an entirely different product. For instance, shifting from Dynamics AX to Dynamics 365 Finance & Operations—or from an on-premise legacy system to Business Central’s cloud platform—is a migration
This process often involves re-configuring data, rebuilding customizations, and leaving behind outdated workflows or redundant historical data
Migrations are transformative, enabling businesses to adopt modern architectures but requiring more planning and resource investment.
Factors to Consider When Deciding
1. Current System Limitations
If your existing solution (e.g., Dynamics NAV 2016 or older) is no longer supported or lacks critical features, an upgrade to Business Central may suffice. However, if your system is heavily customized or incompatible with newer platforms, migration might be necessary to avoid technical debt
2. Business Goals and Scalability
Evaluate your long-term needs. Upgrades are cost-effective for incremental improvements, while migrations support broader digital transformation. For example, moving to Business Central’s cloud environment offers scalability, real-time collaboration, and enhanced security—key benefits for distributed teams
3. Customization and Data Complexity
Upgrades work well if your customizations are compatible with newer versions. Migrations, however, may require rebuilding integrations or simplifying processes, which can extend timelines
Cost, Complexity, and Timeline: A Side-by-Side Comparison
| ASPECT | UPGRADE | MIGRATION |
| Cost | Lower upfront costs (data conversion tools) | Higher due to re-implementation and training |
| Complexity | Moderate (existing workflows retained) | High (data mapping, customization rebuilds) |
| Timeline | Weeks to months | Months to a year |
For example, a small business with minimal customizations might upgrade to Business Central in 3–6 months, while a large enterprise migrating from Dynamics AX could take 12+ months
When to Choose Each Path
- Opt for an Upgrade If:
- Your current system is a recent version of Dynamics NAV
- You prioritize speed and cost efficiency
- Core processes are stable and require minimal changes
- Opt for a Migration If:
- You’re moving from an unsupported or legacy platform (e.g., Dynamics AX)
- You need advanced cloud capabilities (e.g., AI, Power Platform integration).
- Your business model demands scalability and agility
Why Business Central Should Be Your End Goal
Regardless of the path, Dynamics 365 Business Central offers unparalleled advantages. Its cloud-native architecture ensures anywhere access, robust security, and seamless integration with Microsoft 365 tools like Teams and Power BI
Companies that migrate or upgrade often report improved productivity, cost predictability, and faster decision-making
