This section describes how to upgrade vCenter Servers from 8.0b or 8.0 U1 to 8.0 U1d in Active, Passive, and Witness nodes, if your vCenter Server Appliance is configured in a vCenter High Availability (HA) cluster. If you are already using vCenter Server 8.0 U1d in the Telco Cloud Platform 5G Edition 3.0 environment, vCenter Server upgrade is not required for Telco Cloud Platform 5G Edition 3.1.



The upgrade sequence of the vCenter Server VMs must be Witness => Passive => Active.



vCenter Server is upgraded successfully and all services are up and running.
