I have created a backup set through RMAN to a particular disk location:
But for some reason, say to reorganize files on my disk, I need to change this to another disk:

So I first physically copy the backuppiece to the new location. But how do I let RMAN know of this new location ? Its too bad that CATALOG command cannot be used to re-catalog backup pieces or backup sets. It will only work for controlfilecopy, datafilecopy and archivelog.

Is ther any way this can be done "legally" without making adhoc updates to catalog tables ? If so, please let me know. this question has pained me from a long time!!
