Restore RMAN backup on new server

Question

Hi
I took RMAN backup of a database with control file autobackup on...I copied the backup
to a new server restored the spfile from the backup and modified the parameters
bdump,udump,control file because the directory structure is different from the original
machine.I restored the control file and it was restored properly.
Now I need to restore the datafiles in the new path so I used set newname and switch
but I get some error ....I have posted the error please look at it
RMAN> run

Answer 1

Try to clear and recatalog the backups to be used, before the restore:
rman target /
crosscheck backup;
delete expired backup;
catalog start with 'path_to_your_backup';
