28.7. Renaming a Server or Replica Host System

There is no way to change the hostname for an IdM server or replica machine. The Kerberos keys and certificate management is too complex to allow the hostname to change.
Rather, if a server or replica needs to be renamed, it is easier to replace the instance.
  1. Create a new replica, with a CA, with the new hostname or IP address. This is described in Chapter 4, Setting up IdM Replicas.
  2. Stop the original IdM server instance. 
    [root@oldserver ~]# ipactl stop
  3. Verify that all other servers/replicas and clients are working as before.
  4. Uninstall the IdM server, as in Chapter 7, Uninstalling IdM Servers and Replicas
