Infrastructure Briefing — October 15, 2025

Executive briefing: VMware’s product lifecycle matrix lists 15 October 2025 as the end of General Support for vSphere 7. After this date, only limited Technical Guidance is available, without security advisories or hardware certification updates. Virtualization teams must finalize migrations to vSphere 8, validate hardware/driver compatibility, and adjust support contracts to maintain patch coverage.

Key risk themes

• Security patch gap. Technical Guidance omits critical and security patches, leaving ESXi 7 hosts exposed to hypervisor CVEs.
• Hardware and firmware drift. OEM compatibility guides will stop certifying new server and HBA firmware for vSphere 7, increasing instability risk.
• Supportability. Vendors may decline case support for issues on out-of-support hypervisors, affecting SLA commitments.

Operational priorities

• Upgrade runway. Map clusters to upgrade windows, sequencing vCenter, ESXi hosts, and lifecycle manager baselines toward vSphere 8 with rollback plans.
• Hardware validation. Cross-check server, NIC, and storage controller firmware against the vSphere 8 compatibility guide before scheduling upgrades.
• Backup and DR readiness. Ensure backup proxies, replication appliances, and monitoring agents are certified for vSphere 8 before host cutovers.

Enablement moves

• Communicate the end-of-support date and Technical Guidance limitations to application owners and managed service partners.
• Refresh SOPs for host evacuation, lifecycle manager baselines, and firmware sequencing to minimize maintenance window overruns.
