Dynamics NAV to Business Central Upgrade
Upgrade or reimplement from Dynamics NAV to Business Central online, with your customizations triaged, rebuilt as extensions where they still earn their place, and your data moved safely.
Hull Technologies moves Dynamics NAV customers to Business Central online by the route that fits: a full upgrade that keeps history, or a reimplementation that leaves old customizations behind. We triage every C/AL change, rebuild the ones you still need as AL extensions and test the data before cutover.
Key facts
- NAV 2018, the final NAV release, leaves extended support on 11 January 2028; NAV 2017 on 11 January 2027.
- Every NAV version must pass through Business Central 14 on-premises before it can reach Business Central online.
- A full upgrade keeps history but every C/AL customization must become an AL extension.
- A reimplementation moves master data, open documents, balances and setup, and leaves legacy code behind.
Upgrade or reimplement?
Microsoft describes both paths in Migrate Dynamics NAV to Business Central online. Our NAV upgrade vs reimplementation guide sets out when each wins.
What happens to your customizations
We inventory every customization and sort it into keep, replace with standard features or an app, or retire. What you keep is rebuilt as AL extensions, as described in our guide to converting NAV C/AL customizations to AL extensions.

Questions buyers ask us
How long does a NAV upgrade take?
It depends on your version, the number of customizations and data size. Older versions need more upgrade hops, so the assessment gives you a dated plan.
Can we stay on-premises?
Business Central is also available on-premises, but most NAV customers choose Business Central online for automatic updates and lower infrastructure work.
