Decommission and remove an external Platform Services Controller for Windows from the vSphere inventory.

After converging an external Platform Services Controller node to a vCenter Server appliance, decommission the original external Platform Services Controller. Decommissioning a Platform Services Controller shuts it down and removes it from the single sign-on domain.


Make sure no vCenter Server instances are pointing to the Platform Services Controller before decommissioning.

Reconfigure any products deployed into the environment that use the Platform Services Controller to use the newly deployed vCenter Server appliance.

Make a backup of the Platform Services Controller before decommissioning to ensure no loss of data.


  1. On the Windows computer running Platform Services Controller, click Start > Run, type cmd, and click OK.
    The Command Prompt opens.
  2. Navigate to the directory C:\Program Files\VMware\vCenter Server\bin\
  3. Unregister the stopped Platform Services Controller appliance using the cmsso-util unregister command.
    Where, Platform_Services_Controller_System is the FQDN or IP address of the Platform Services Controller that you want to decommission. Run this command only on one of the Platform Services Controller replication partners, as the synchronization removes the entries from all other Platform Services Controller replication partners. Enter the vCenter_Single_Sign_On_password in quotes.
    Note: The cmsso-util unregister command restarts the services on the Platform Services Controller on which you are running the command. It can take several minutes for the command to finish.
    cmsso-util unregister --node-pnid Platform_Services_Controller_System --username administrator@your_domain_name --passwd 'vCenter_Single_Sign_On_password'
  4. Remove the Platform Services Controller appliance that you no longer need from the vSphere inventory.

What to do next

You can delete the virtual machine for the decommissioned Platform Services Controller.

Ensure that any external solutions or products are registered with the new vCenter Server appliance.
