Posted on Updated on

Version tracking is the backbone of lifecycle management. Whether you are patching against the latest security vulnerability or verifying compatibility for a backup agent, you need the exact build number.

Below is the comprehensive history of vCenter Server, from the cutting-edge vSphere 9.0 down to the legacy VirtualCenter 2.5.

Quick Tips for the Lazy Admin

  1. Check via VAMI: For 6.7 and newer, go to https://<vcenter-ip>:5480. The version and build are right on the login screen.
  2. Compatibility: Before upgrading vCenter, check the VMware Interoperability Matrix. Just because vCenter 9.0 is out doesn’t mean your older ESXi 6.7 hosts can talk to it!
  3. VCSA Migration: If you are still on version 6.5 or 6.7, your next step is a migration to the Appliance (VCSA). There is no “in-place” upgrade for Windows-based vCenter to 7.0+.

Is your host up to date? Checking the “About” section in your vSphere Client is step one, but cross-referencing that number against this list is how you confirm if you’re on a General Availability (GA) release, an Update, or an Express Patch.

How to Verify Your Build Number

If you aren’t at your desk and only have SSH access to the host, you can find your build number instantly with this command:

vmware -v

Example Output:

VMware ESXi 8.0.0 build-20513097

Lazy Admin Tip 💡

Always remember the vCenter Interoperability Rule: Your vCenter Server must always be at a build version equal to or higher than your ESXi hosts. If you patch your hosts to vSphere 9.0 while vCenter is still on 8.0, your hosts will show as “Not Responding” or “Disconnected.”
