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
Upgrade to a supported PHP 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.
Buy more time
Some vendors sell extended or paid security support after the standard end date. Check the vendor's lifecycle page for this version.
