Cisco Unified Communications — EOL / EOSL Planning Guide
Best practices for upgrading and lifecycle management
- Track EOL announcements and sort by the earliest lifecycle date above.
- Shortlist successor models per series and verify feature and performance parity.
- Bundle hardware refresh with OS and software upgrades to minimize maintenance windows.
- Stage deployments and keep rollback plans ready before hitting EOSL dates.
