Cloud tiering appliance, how to migrate repository to new CIFS server

Does documentation exist for migrating the repository? I see several docs that say this is possible but, they go into no other detail on the specifics. We recently went from a Celerra 480 to a VNX 5700, all file systems were replicated over to the VNX including the archive_fs that we use for our repository, most of our file systems were setup with our primary CIFS server but due to some initial setup issue we have some departmental data being stubbed on a secondary "test" server. I have not set up this secondary server on the VNX but would like to move the existing data from the secondary CIFS server on the Celerra to the New primary on the VNX and then re-stub. Is there an easy or detailed process for achieving this?
