We have five vCenter servers in linked mode running vCenter 6.7 U3g. I’m preparing to update next week to vCenter 6.7 U3j.
Is it best practice to shut down all five vCenter servers at once, then take snapshots of all five vCenter servers? Or, is it ok to shut down one vCenter, take the snapshot, power up and update that vCenter server, then go on to the next? I wasn’t sure if due to replication, it would be best to snapshot them all at about the same time, in case all five vCenter servers would need to be rolled back due to issues.
