Thanks a lot for the response.
But, my question is not about restoring the the datafiles into a different directory structure. Its about my current backup location.

On the primary database backup is on /u01, but on the new host its copied on /u02. So, if i need to restore this backup from /u02 using RMAN, this has to be cataloged into rman repository. Hence, i wanted to know, if i should catalog this in the rman repository on new host or the primary host.
Also, during restore operation on the new host, should i connect to rman reposritory have backup info on /u01.
