After twenty-five years of guiding companies through ERP transitions, I’ve noticed something that rarely changes: the businesses that struggle with a NAV to Business Central move aren’t the ones with the messiest data or the most complicated customizations. They’re the ones that treated it as an IT team’s project from day one, rather than a business decision that happens to involve technology.
That distinction matters more than most people expect going in.
Every migration I’ve worked on that went well started the same way, with an honest look in the mirror. Not a rushed audit, but real clarity about how the current system is actually being used, which processes have quietly outgrown their original purpose, and where the complexity in the business genuinely lives versus where it’s just historical baggage nobody’s gotten around to cleaning up. Skip that step, and you’re not choosing a path forward so much as guessing at one.
Once that picture is clear, a company generally lands on one of two routes. Some are better served by building on the foundation they already have, upgrading in a structured, deliberate way that respects the customizations earning their keep. Others do better wiping the slate cleaner and adopting standard Business Central processes rather than recreating old habits in a new system. I don’t think one approach is objectively smarter than the other. It depends entirely on where the complexity sits and what the business actually needs three years from now, not just what feels safest today.
Here’s the part that tends to get underestimated, though: the work that really matters starts after go-live, not before it. That’s when companies begin digitizing workflows in earnest, automating the manual steps that used to eat up someone’s afternoon, and tightening up daily operations in ways that compound over time. Tasks that once required coordination between three people and a spreadsheet start happening inside the system itself. And because the platform keeps evolving on its own, the business doesn’t need a new project every time a requirement changes. That ongoing rhythm of insight, careful execution, and continuous refinement is what actually produces results that hold up over years, not just at the ribbon-cutting.
Two Roads, Same Destination
Companies planning a move from NAV to Business Central usually reach a fork fairly early, which of two reasonable paths gets them where they need to go.
Business Central as the Natural Next Step
Business Central is the direct successor to NAV, built from the ground up as a cloud-native platform that can scale with a growing business. Moving to it means the latest capabilities arrive automatically, maintenance stops being something IT team has to schedule around, and the system simply stays current without anyone chasing it.
We’ve never treated this as a straightforward system upgrade, and we’d caution anyone who does. It’s a strategic decision with real business consequences, and it deserves to be approached that way. Our focus has always been making sure the investment in Business Central does more than modernize the technology stack, it should create business value that outlasts the project itself, without disrupting the operations people depend on every day.
In practical terms, that means a platform built on Microsoft’s current technology rather than something already trailing behind, automatic access to new capabilities as Microsoft ships them, and enough scalability that the system isn’t the thing holding growth back two years from now.
Our Approach: Keep What’s Working, Simplify What Isn’t
Having specialized in NAV to Business Central upgrades for a long time now, we’ve settled on a two-path approach because, frankly, forcing every client down the same route never made sense to us. Some organizations should modernize their existing customizations and build on a foundation that’s already proven itself. Others are better off simplifying and rethinking processes around what Business Central offers out of the box.
That flexibility matters because it means a company doesn’t have to choose between keeping what makes its operations distinctive and gaining the benefits of a modern, cloud-based platform. Both are possible at once. And the relationship doesn’t end at go-live, ongoing Keep Current maintenance is what keeps the system effective months and years later, not just on the day it launches.
In practice, this looks like two clear paths forward, building on existing customizations or simplifying with standard functionality, legacy C/AL code converted into modern AL extensions, and Keep Current maintenance running continuously to keep pace with the business rather than falling behind it.
How the Upgrade Actually Unfolds
A NAV to Business Central upgrade with us follows a process we’ve refined over many implementations, precisely because we’ve learned where things tend to go wrong. It starts with a full data migration, ensuring historical records move over intact. That history matters more than people realize until they’re missing it.
From there, we run targeted workshops focused on Quote-to-Cash and Procure-to-Pay, since these are usually where the real operational friction hides. Existing customizations get converted from C/AL into modern AL extensions, and integrations are redesigned around current, well-supported APIs rather than patched together to survive one more year. The process wraps up with proper user training, automated testing, and a go-live supported by hypercare, followed by the same Keep Current maintenance that keeps the system relevant well after the project team has moved on.
None of this is complicated in theory. What separates a smooth transition from a painful one is usually discipline in the execution, not cleverness in the planning.
Considering Your Next Step?
If you’re still running an older NAV(Navision) system, you’ve probably already asked yourself whether it’s time to move. There’s rarely a perfect moment to decide, but there is a right way to go about it once you do.
At Chang Ting, we upgrade businesses safely to Dynamics 365 Business Central through a proven programme that pairs full data migration with targeted business process workshops. It’s the same principle we’ve talked about above, you keep what already works, and you get the full value the modern platform has to offer, nothing lost in the move, and a lot gained.
If that sounds like where you’re headed, we’re happy to talk it through.
