You reregister a previously registered plug-in solution and any third-party client plug-in packages with vCenter Server after the SSL certificate has been refreshed following an upgrade or migration.

Consult the vendor documentation for any solution-based vCenter Server extensions and client plug-ins for instructions to re-register after a vCenter Server upgrade or migration.

If the procedure provided by your plug-in solution vendor fails to reregister the plug-in, you can use the following procedure to remove the plug-in registration, and then register it again with vCenter Server. For information on registering plug-ins, see the vCenter Server and Host Management documentation. For information on removing or disabling unwanted plug-ins from vCenter Server, see Knowledge Base article KB 102536.

Procedure

  1. In a Web browser, navigate to the Managed Object Browser of your vCenter Server.
    https://vcenter_server_ip_address_or_fqdn/mob/?moid=ExtensionManager
  2. Log in with your vCenter Server credentials.
  3. On the ManagedObjectReference:ExtensionManager page, under Methods, click UnregisterExtension.
  4. On the void UnregisterExtension page, in the text box inside the Value column, enter the value for the key property of the Extension data object of your vSphere Client extension.
  5. To unregister the extension click Invoke Method.

What to do next

Go to the solution registration page and register the plug-in.

Verify that your extension is registered successfully with vCenter Server by using one of the following approaches.
  • In the vSphere Client, go to Administration and under Solutions, select Client Plug-Ins and click Check for New Plug-Ins.
  • Log out and log in again to the vSphere Client. The vSphere Client checks for new plug-ins for each new user session
