Rename a vCenter client

2. In the domain tree, select the vCenter client.
3. Click MORE ACTIONS > Edit Client.
   The Edit Client window is displayed.
4. In the Name field, type the new fully qualified DNS name.
5. Click UPDATE.
   A confirmation message is displayed.
6. Open a command shell and log in by using one of the following methods:
   • For a single-node server, log in to the server as admin.
   • For a multi-node server:
