This will only be possible using the agentless option, it is not possible to restore to a different DC using the agent based restore method. Due to the agentless method being the only option to restore, it will not be possible to restore the objects password or SID History. Unless the password and SID history has been previously configured to be restored in the domain (preserved in the backup being used.

A full system state restore (via repair wizard) will not be possible as system stare restores require that the backup be restored to the same machine in which it came from.
