If you run ESXi, you're managing two countdowns at once — and they interact badly. Clock one: support dates. vSphere/ESXi 7.x reached end of general support on October 2, 2025 (Broadcom extended it six months from the original April date — a one-time mercy, already spent). After end of general support: no more bug fixes or security patches, no support cases. Hypervisors are a top-tier attack target; an unpatched hypervisor is a very different risk than an unpatched app server, because everything above it inherits the compromise.
Clock two: licensing. Broadcom killed perpetual licenses in December 2023. Everything is subscription now, bundles have consolidated, and renewal quotes have become the stuff of sysadmin forum legend. The practical effect: staying current with VMware isn't just an upgrade project anymore, it's a recurring budget line that many orgs are re-evaluating from scratch.
Plenty of teams responded to the licensing shock by freezing — staying on 7.x, skipping the renewal, running on inertia. That converts a licensing problem into a security problem: you're now on an unsupported hypervisor with no patch path, which is strictly worse than either paying up or migrating.
Whatever the choice, it should be made by a date on a calendar, not by drift. Every ESXi version's current status is tracked live at endoflife.ai/esxi — and the rest of your stack's deadlines (SharePoint and SQL Server 2016 just died July 14; OpenSSL 3.0, .NET 8/9, PostgreSQL 14, and PHP 8.2 all go before year-end) are at endoflife.ai/eol-watch.
