When you deploy a vCenter Server, you select an environment. For vCenter HA, Small, Medium, Large, and X-Large are supported for production environments. If you need more space and want to change the environment, you have to delete the Passive node virtual machine before you change the configuration.


  1. Log in to the Active node with the vSphere Client, edit the cluster configuration, and select Disable.
  2. Delete the Passive node virtual machine.
  3. Change the vCenter Server configuration for the Active node, for example, from a Small environment to a Medium environment.
  4. Reconfigure vCenter HA.
