ResNav warns employers to preserve payroll records before Dynamics GP sunsets

ResNav is urging companies still using Microsoft Dynamics GP payroll to build a separate plan for historical payroll and HR records before mainstream support ends on Dec. 31, 2029. The company says many employers will lose audit-ready documents unless they archive them before migrating to a new payroll or HCM system.

Why it matters: - Payroll and HR data often outlive the system that stores them. - If employers migrate without preserving historical records, they may lose access to documents needed for audits, wage claims, litigation and unemployment disputes. - Keeping a legacy Dynamics GP environment running just to answer records requests can add ongoing licensing, hosting and IT costs.

What happened: - ResNav is warning organizations using Microsoft Dynamics GP to treat historical record preservation as a separate migration workstream. - Microsoft stopped selling new Dynamics GP licenses earlier this year. - Mainstream support for Dynamics GP is scheduled to end Dec. 31, 2029. - Discretionary security patches are expected to continue at most through April 30, 2031. - Older GP versions covered by Microsoft's Fixed Lifecycle Policy may reach their effective deadline before 2029.

The details: - New payroll and human capital management platforms usually move forward only current data. - Historical payroll and HR records left inside Dynamics GP need their own migration plan. - ResNav says source documents such as pay stubs, tax forms and personnel files have separate retention and audit requirements. - The company recommends preserving both the data and the supporting documents, not just exporting rows from the system. - Gabe Bell, vice president of sales at ResNav, said employers often assume historical information will move automatically, but that rarely happens. - Bell said legacy data is often impossible to recover after a system is decommissioned. - Bell said planning before go-live is cheaper and simpler than reconstructing records later. - ResNav says organizations migrating off GP usually face three choices: keep the legacy system alive, export static files, or move historical data and documents into a dedicated archive. - ResNav recommends the archive approach for most organizations. - ResNav says that recommendation applies whether the new platform is Dynamics 365 Business Central or a cloud HCM system such as ADP, UKG, Workday, Paycor or Paylocity. - ResNav points readers to its resource, Dynamics GP Payroll Is Being Retired: What's Next?, for the full end-of-life timeline.

Between the lines: - The warning is not just about software replacement. - It is about preserving compliance evidence that can surface years after a migration. - Employers that delay may face a harder choice between costly legacy support and incomplete records. - The pressure is growing because wage-and-hour investigations can reach back farther than many employers expect, and some state record-retention rules are longer than common corporate retention habits.

What's next: - Employers still on Dynamics GP will need to decide whether to archive records before switching systems. - Organizations choosing a new payroll or HCM platform will need to map what data moves, what stays behind and what must be preserved separately. - ResNav is positioning historical archive planning as part of the migration, not an afterthought.

The bottom line: - Dynamics GP’s sunset is turning payroll migration into a records-retention issue, and ResNav says the safest move is to archive historical payroll and HR documents before the old system goes dark.
