End of support

Dynamics GP end of support is not just an information technology deadline.

Mainstream support for Dynamics GP has ended, and Microsoft has set April 30, 2031 as the date for the final security update. When that date passes, the risk is not a missed feature. It is security you cannot patch, payroll and tax tables that stop updating, no one to call when finance goes down, and a bill that climbs every year you wait.

Deadline: end of security updates

Microsoft ends security updates for Dynamics GP on April 30, 2031. After that date there are no security patches, no payroll and tax table updates, and no support line to call when finance goes down. Count the runway to your migration below.

Security risk

Unpatched and exposed

No security updates means no defense against new vulnerabilities. Auditors, insurers, and customers increasingly treat unsupported enterprise resource planning as a failed control, well before anything is breached.

Payroll and tax risk

Updates simply stop

Dynamics GP payroll tax tables, year end formats, and regulatory updates stop arriving. Your finance team is left filing against rules the software no longer knows about.

Talent risk

No one left who knows GP

Partners retire their Dynamics GP practices and the developers who know Dexterity retire with them. When finance goes down at month end, there is no escalation path left.

Cost risk

The bill only climbs

Enhancement premiums, emergency fixes, and rising hosting all compound. Wait until the deadline nears and you migrate in a scramble, with partner capacity booked and far less room to negotiate.

Will we lose our data?

No. Your data, history, and customizations come across cleanly.

It is the first question every Dynamics GP team asks. The honest answer: nothing is thrown away. Master records and history lift across and are reconciled to your live GP totals. Your customizations are rebuilt as supported Business Central extensions. Here is the split, what lifts cleanly, what we rebuild as modern extensions, and what we retire by design.

Comes across cleanlyRebuilt as modern extensionRetired by design

Master and reference data

Accounts, customers, vendors, items, and analytical dimensions, lifted and reconciled to your live Dynamics GP totals.

Transactions and history

Open and posted transactions, general ledger detail, and year end balances, reconciled to the dollar before cutover.

Posting and currency setup

Posting accounts, number sequences, payment terms, currencies, and tax configuration carried across exactly as set.

Dexterity and Modifier changes

Dexterity code and Modifier with Visual Basic for Applications customizations are re coded as supported Business Central extensions, with the business logic preserved.

SmartList and reports

SmartList views and classic report layouts are rebuilt on Business Central, with Power BI taking over most analytics natively.

Integrations and connectors

Integration Manager and eConnect feeds are re architected to modern Business Central application interfaces and webhooks.

Dead customizations

Unused objects the discovery surfaces are left behind, not carried forward into the new environment.

Obsolete reports

Report layouts no one has run in years are retired instead of rebuilt, with a documented record of the decision.

Legacy data and add ons

Sandbox, test, and duplicate records stay in the archive. Add ons with a native Business Central or AppSource equivalent are swapped.

The migration process

A controlled move, week by week.

Twelve weeks, fixed scope locked at the start. Here is what happens each week, from discovery to go live and hypercare. Stages overlap by design, so your team is never offline for more than a single planned window.

Get A Free Migration Assessment Estimate The Cost Of Staying

Cost

Most Dynamics GP to Business Central migrations land between forty thousand and one hundred seventy five thousand dollars, driven by user count, the number of customizations, and the integrations that come across. You leave the assessment with a fixed scope range, not an open ended estimate. The calculator on this page sizes it against your own environment.

Most teams recover what they spend keeping Dynamics GP alive: on premises servers, information technology upkeep, manual reporting, and the enhancement plan. For a typical mid sized environment that is often tens of thousands of dollars a year. The calculator on this page shows your own figure.

History and customization

Your open and posted transactions, ledger history, and year end balances move into Business Central and are reconciled to your live Dynamics GP totals to the dollar before cutover. Master records like accounts, customers, vendors, and items come across with their setup intact.

Dexterity, Modifier with Visual Basic for Applications, and SmartList customizations are mapped during discovery and rebuilt as supported Business Central extensions or native features. Integration Manager and eConnect feeds are re architected to modern Business Central application interfaces, so the business logic is preserved without legacy bolt ons.

Timeline and risk

Most projects run eight to sixteen weeks end to end. Discovery and planning take two to four weeks, re platforming and data migration take four to ten weeks, and cutover plus hypercare close the engagement. You get the full milestone schedule in the assessment.

Near zero. A parallel run validation phase runs before cutover, then go live ships over a single planned weekend window, so your team is never offline during business hours.

The cost and the risk both climb. You keep paying for servers, upkeep, and enhancement plans while losing security patches, payroll and tax updates, and Microsoft support. Auditors and insurers increasingly treat unsupported enterprise resource planning as a failed control. Confirm your exact end of support date on the Microsoft lifecycle pages and plan back from there.
