Notes: Fixed Lifecycle Policy. Start, mainstream end and extended end dates from Microsoft's lifecycle page for this version (start date shown as the release date). Microsoft documents a direct upgrade path from this version to Business Central on-premises (version 14). Microsoft's July 2026 Dynamics 365 blog post on NAV, GP and SL also gives January 2028 as the end of extended support for the final NAV version. Product-wide, from April 30, 2031 Microsoft ends NAV Service Plan coverage, sales of additional perpetual users and renewal of NAV subscription licences.

What the end of support means
- Mainstream support usually includes bug fixes, security updates and (for ERP) regulatory and tax updates. When it ends, non-security fixes and new features stop.
- Extended support usually means security updates only. Exact terms differ by vendor and may require a support contract.
- After the final end date the software keeps running, but the vendor no longer ships fixes or security patches. Known vulnerabilities stay open, and compliance or cyber-insurance requirements may treat it as unsupported software.
Upgrade paths
Move to Dynamics 365 Business Central (on-premises)
This is the successor recorded for this version (see notes and sources).
Upgrade to a supported Microsoft Dynamics NAV version
Staying on the same product usually means the least retraining. Check the upgrade path and system requirements in the vendor documentation; some upgrades must go through an intermediate version.
Re-platform to a different ERP
An end of support is a natural point to compare other systems, including cloud ERP. Re-platforming is usually a bigger project than a version upgrade, so compare total cost over several years, not just the first year.
Stay put for now (with risks)
The software keeps running after support ends, but without vendor fixes, tax/regulatory updates or security patches. Third-party support, where available, is not vendor support and cannot provide vendor patches.
