Best Practices
• If the current vCenter Server environment is reused, take the following steps. If a new vCenter Server is used,
skip this step. We have tested the upgrade without uninstalling vCenter Server. Although it was successful, we
recommend removing it every time to prevent any unexpected performance or results.
– Uninstall vCenter Server.
– Reboot the vCenter Server host.
• In both cases, vCenter Server must be reinstalled.
– Install vCenter Server.
