A Dynamics NAV to Business Central migration can move companies from almost any NAV version to the current release of , but the path depends heavily on the NAV version currently in use. Older NAV environments may require several intermediate upgrades, with each stage involving code conversion, data validation, and testing. Understanding the starting point, existing customizations, and available migration options is essential for developing a realistic timeline and budget.
Key Highlights
- The Dynamics NAV to Business Central migration path depends on the version of NAV currently in use.
- Older NAV versions may require multiple intermediate upgrades before reaching Business Central.
- Customizations, undocumented workarounds, and accumulated technical debt can increase migration complexity and cost.
- Microsoft does not support skipping required upgrade stages.
- An upgrade assessment can help determine whether a technical upgrade or reimplementation is the better approach.
Can You Move Directly From Dynamics NAV to Business Central?
Usually, no. treat a Dynamics NAV to Business Central migration as a series of steps rather than one direct jump from an older NAV version to the latest Business Central release.
The starting NAV version makes a significant difference. NAV 2018 and Business Central On-premises from October 2018 can move directly to Business Central version 14 and then continue to current releases. NAV 2013 must first be upgraded to NAV 2018 and then to version 14, while NAV 2015 can move directly to NAV 2018.
Companies still running NAV 2009 generally face a longer route. These environments typically need to pass through a mid-2010s NAV release before reaching version 14. Each stage requires its own technical work, including converting code from C/AL to AL, rebuilding customizations as extensions, migrating data, and testing the resulting system.
In other words, the older the NAV environment, the more likely the migration will involve multiple intermediate stages.
Why Does a Dynamics NAV to Business Central Migration Cost More for Older Versions?
The number of upgrade steps is only part of the reason. Technical debt and accumulated customizations are often what make older Dynamics NAV to Business Central migrations more complicated and expensive.
Over time, businesses tend to develop workarounds to address limitations or specific requirements in their ERP system. Some of those workarounds may no longer be necessary because Business Central now includes functionality that addresses the same business need.
Customizations also need to be evaluated individually. A feature that was custom-developed in an older NAV environment may now be available through standard Business Central functionality or an extension. Recreating every customization without first asking whether it is still necessary can add work and cost to the migration without providing a corresponding business benefit.
This is why companies that have waited the longest often need to take a closer look at their existing processes before deciding exactly what should move to Business Central.
What Happens to NAV Customizations During a Business Central Migration?
NAV customizations require particular attention because the development approach has changed. As part of the upgrade process, code may need to be converted from C/AL to AL, while existing customizations are rebuilt as extensions.
That work takes place alongside data migration and testing. As a result, each intermediate upgrade can become a project of its own rather than simply another technical step in one larger migration.
For companies with years of custom development, the migration also creates an opportunity to determine which modifications are still important to the business. If Business Central already provides equivalent functionality, there may be little reason to recreate an older customization.
Is There a Way to Shorten the Migration Path?
There are no Microsoft-recommended pathways for skipping required upgrade stages. However, having a clear migration plan and working with a knowledgeable partner can help companies avoid unnecessary complications and mistakes.
Companies considering a Dynamics NAV to Business Central migration may have several options depending on their NAV version and environment. Evaluating those options early can help prevent the project from becoming more complicated than necessary.
Microsoft has also introduced the Bridge to the Cloud program, which is designed to help smooth the migration process and lower overall costs. It does not eliminate critical upgrade steps, but it can change the economics and reduce the chances of errors during the transition.
What Is the First Step in a Dynamics NAV to Business Central Migration?
The best first step is to determine exactly where the existing NAV environment stands before selecting a target migration date.
An upgrade assessment can map the current NAV version, customizations, ISV solutions, and the realistic path from the existing environment to Business Central. For some companies, that may result in a relatively straightforward technical upgrade. For others, particularly organizations running older NAV releases with years of custom code, a reimplementation may make more sense than moving through every intermediate stage.
The assessment turns a general goal such as “we should move to the cloud eventually” into something more concrete: an estimated path, timeline, and level of effort.
That is important because no two Dynamics NAV to Business Central migrations are necessarily alike. Even companies running the same NAV version can face very different projects based on their customizations, processes, and ISV solutions.
Should You Upgrade NAV or Implement Business Central?
For some organizations, upgrading the existing NAV environment is the logical approach. For others, especially companies running very old NAV versions with substantial custom code, reimplementation may be worth considering.
The decision depends on the condition of the existing system and the effort required to preserve it. An assessment can help determine whether moving the current environment forward is practical or whether starting with a cleaner Business Central implementation would make more sense.
The objective should not simply be to complete every technical upgrade step. It should be to establish the most practical path from the system the company has today to the Business Central environment it needs going forward.
Frequently Asked Questions About Dynamics NAV to Business Central Migration
Can NAV 2018 move directly to Business Central?
Yes. NAV 2018 and Business Central On-premises from October 2018 can move directly to Business Central version 14 before continuing to current releases.
Can NAV 2013 move directly to Business Central?
No. NAV 2013 must first be upgraded to NAV 2018 and then to Business Central version 14.
Does NAV 2009 require multiple upgrade steps?
Yes. NAV 2009 environments generally need to move through a mid-2010s NAV release before reaching version 14. Each stage involves code conversion, data migration, and testing.
Can a company skip an intermediate NAV upgrade?
No. Microsoft does not support skipping required stages in the documented upgrade path.
What should a company do before starting a NAV to Business Central migration?
An upgrade assessment can identify the current NAV version, customizations, ISV solutions, and a realistic migration path. This information provides a better basis for determining the project's complexity, timeline, and cost.
Take the Next Step in Your Dynamics NAV to Business Central Migration
A Dynamics NAV to Business Central migration does not have to begin with choosing a target date. It should begin with understanding the current environment and determining what the most practical path forward looks like.
For some organizations, that means planning a technical upgrade. For others, it may mean evaluating reimplementation or taking advantage of programs designed to support the transition to the cloud. Either way, understanding the path before committing to the project can help replace assumptions with a migration plan based on the actual condition of the NAV environment.
