I would keep using the catalog. Be sure to copy the files to directories with the same name[s] as on host A. rman stores/reads the files local to the database so I can not imagine it checks for the original hostname. Do you use the correct copy syntax ? Don't create a host B catalog; just use the original one. Start the target instance nomount and perform the copy operation you want. It should work.

Maybe you should hire a consultant to help you out. Ronald.
