Prerequisites: Take a valid offline snapshot or backup of the vCenter Server Appliance (VCSA) before proceeding. For Enhanced Linked Mode, power off all linked vCenters and take snapshots simultaneously. Refer VMware vCenter in Enhanced Linked Mode pre-changes snapshot (online or offline) best practice.
If using vCenter HA, destroy the VCHA configuration before taking snapshots.
