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.
- Extended Security Updates (ESU) extends security fixes for a limited time for a fee. Treat it as a bridge to an upgrade.
Upgrade paths
Upgrade to a supported Windows Server 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.
