After migrating to new MS DPM 2007 server, how do I set up end-user recovery?

We migrated to a new DPM server.  We are trying to move the previous version recovery points to look at the new server.  I set the active directory links by going to "C:\Program Files\Microsoft DPM\DPM\End User Recovery" and typed in the domain and active directory server.  I then went to DPM options and checked the enable end-user recovery box.  I restarted the active directory server and the previous version tabs still look at the old DPM server.  What do I have to do to be able to recover from the new server at the end-user level?
