For the everyday VI admin that is tasked or will be asked to ensure vCenter is patched when a VMware Security Advisory is released, I hope that you find the following video as a helpful guide to go through a vCenter patch process. Please coordinate with your in-house security teams, and proper maintenance windows, ensure snapshots are taken, try to achieve as much prep work as possible to make your change go smoother.
For multiple vCenters that are in Enhanced LinkedMode, ensure you take cold snapshots (VCSA Powered Off) of every vCenter. Also, in the event you have to revert back one of the vCenters, you must revert all of them at the same time.
Also, be aware if you are running any solutions that are provided by vendors that provide lifecycle automation that you coordinate with your support and account teams before going to the next version or patch.
