If you have deployed or installed two or more joined instances of vCenter Server with an embedded Platform Services Controller, you can reconfigure them as multiple vCenter Server instances that are using joined external Platform Services Controller instances.

Before you begin

  • For each vCenter Single Sign-On site, deploy or install an external Platform Services Controller instance as a replication partner of an existing embedded Platform Services Controller instance from this site.

    Note:

    You can determine the current vCenter Single Sign-On sites by using the vmfad-cli command.

    • For a vCenter Server Appliance with an embedded Platform Services Controller, log in to the appliance shell as root and run the command.

      /usr/lib/vmware-vmafd/bin/vmafd-cli get-site-name --server-name localhost
    • For a Windows installation of vCenter Server instance with an embedded Platform Services Controller, log in to the Windows machine as an administrator, open the Windows command prompt, and run the command.

      C:\Program Files\VMware\vCenter Server\vmafdd\vmafd-cli get-site-name --server-name localhost
  • Create snapshots of the vCenter Server instances with an embedded Platform Services Controller and the external Platform Services Controller instances, so that you can revert to the snapshots if the reconfiguration fails.

Transition step

Note:

The reconfiguration of a vCenter Server instance with an embedded Platform Services Controller and repointing it to an external Platform Services Controller instance is a one-way process after which you cannot switch back to vCenter Server with an embedded Platform Services Controller.
