Mixed vCenter build versions

Jump to solution

If you have multiple vCenters in Enhanced linked mode and all on the same major version of 6.7, do they have to be patched at the same time to keep the same build version or can you do some during one maintenance window and the rest during another?

Better to do together in one maintenance window. Do one VC1 first followed by VC2.

1. Power of both vCSA nodes.
2. Take snapshot of both vCSA nodes.
3. Power on 1st vCSA node. Wait 2 mins and power on 2nd vCSA node.
4. Wait for 10 mins and check if all services on vCSA are up. Should be similar to what we did today. Commands are below what we used today.
5. Once we confirm all the services are up on both vCSA nodes . We are good to upgrade.
6. Upgrade one vCSA at a time. Then follow with second one .

NOTE: If a change must be reverted, all nodes of the Enhanced Linked Mode(ELM) domain have to be restored back to this offline/consistent snapshot.
