Dynamics GP to Business Central migration

Move from Dynamics GP to Microsoft Dynamics 365 Business Central

Microsoft ends product updates, tax and regulatory updates and technical support for the current version of Dynamics GP on 31 December 2029, with security updates only until 30 April 2031. Codestone helps UK businesses on GP plan the move to Business Central on their own timetable, bringing across the history they need.

GP support ends in 2029. The best time to plan is while you still have choices.

Microsoft has confirmed that Dynamics GP retires at the end of 2029. Until then you still get product updates, tax and regulatory changes and technical support. A final stretch of security-only updates follows, ending on 30 April 2031. Older versions run out sooner: GP 2018 support ends on 11 January 2028, and GP 2016 is already unsupported.

If you own your GP licences outright, your system will keep running after each date, but the cover around it gets thinner. Subscription licences can’t be renewed after 30 April 2031. Staying on GP has other costs too:

  • Tax and regulatory updates: these stop at the end of 2029, so any rule change after that has to be handled outside the system
  • Skills: fewer developers work in Dexterity and GP’s older tools, so changes take longer and cost more
  • Infrastructure: you keep paying to run, patch and back up the servers and SQL databases GP depends on
  • Add-ons: third-party GP products will follow Microsoft’s timeline, and some vendors will stop sooner

Plan early and you choose a quiet period for go-live.

Dynamics GP vs Business Central

Business Central keeps the processes your team already knows in finance, sales, purchasing, stock and projects. What changes is how the system is run, updated and extended.

A structured migration, planned around your business

Every GP system is different. We start with what you have today and build a plan around what you need next.

01

Assess

We review your GP version, customisations, third-party add-ons, integrations and data, then confirm the right migration route.

02

Plan

Together we decide what to keep, what Business Central now does as standard and how many years of history to bring. You get a scope, timeline and cost before work starts.

03

Build and migrate

We configure Business Central, rebuild the customisations you still need as extensions and move your data, using Microsoft’s GP migration tool for a move to the cloud.

04

Test and train

Your team tests real processes and reconciles the figures, and we train users on the new system before go-live.

05

Go live and support

We manage the cutover, stay close through the first period end and continue with ongoing Business Central support.

Your data, customisations and integrations

Bring what matters with you.

We work through your GP system piece by piece and agree with you what comes across, what Business Central already does and what can be retired.

What we look after

  • Your historyFor a move to Business Central in the cloud, Microsoft’s migration tool moves setup, master data, open transactions and historical data from GP 2015 or later. We agree with you how many years to bring across.
  • Your customisationsDexterity and VBA changes that still earn their place are rebuilt as Business Central extensions. The rest we retire, often because Business Central now does the job as standard.
  • Your add-onsWe check which of your third-party GP products have Business Central equivalents and recommend alternatives where they don’t.
  • Your integrationsWe map every system GP connects to, from banking and EDI to ecommerce and payroll, and plan how each one connects to Business Central.

Start with a free GP to Business Central assessment

In a half-day session, our Business Central consultants look at your GP system with you and give you a clear picture of what your migration involves.

You will come away with:

  • Which GP version you run, what Microsoft’s support dates mean for you and whether the standard migration tool covers your version
  • An inventory of your customisations, third-party add-ons and integrations, marked keep, replace or retire
  • The migration route that suits you, including how much history to bring
  • A first-cut plan showing the main stages and how long each is likely to take
  • A demonstration of the Business Central features that matter most to how you work, including Copilot if you move to the cloud

Frequently asked questions

When does support for Dynamics GP end?

For the current version of GP, Microsoft ends product updates, tax and regulatory updates and technical support on 31 December 2029, and security updates continue until 30 April 2031. Older versions end sooner: GP 2018 and 2018 R2 on 11 January 2028, while GP 2016 and earlier are already out of support.

Will GP stop working in 2030?

No. GP keeps running, but from 2030 there are no tax or regulatory updates and no technical support. Security updates stop after 30 April 2031, and subscription licences can’t be renewed beyond that date.

Can we bring our GP history across?

Yes. For a move to the cloud, Microsoft’s migration tool can move historical data alongside your master data and open transactions. We agree with you how many years you need.

What if we run an older GP version?

Microsoft’s standard migration tool needs GP 2015 or later. Older versions need an extra step first, which we plan with you during the assessment.

Do we have to move to the cloud?

Business Central runs in the cloud or on-premises, and the migration route differs for each. Some features, including Copilot and the Teams app, are only available in the cloud version. We will recommend the right option during the assessment.

How long does a migration take?

It depends on your GP version, customisations, add-ons and how much history you bring. Your assessment gives you an initial timeline, and a full plan follows before work begins.
