Upgrading vCenter Server

You must unregister the vCenter Plug-in before making vCenter Server upgrades and register the plug-in again after the upgrade. Because vCenter Server upgrades dispose of plugin data, you must also reconfigure clusters and, if needed, management node (mNode) QoSSIOC settings.


  1. Unregister the plug-in from the vCenter with which it is associated.
  2. Upgrade vCenter to the latest version.
  3. Register the plug-in with the upgraded vCenter.
  4. Add clusters using the plug-in.
  5. Optional: Configure management node settings.
