If I upgrade a partition from V6R1M1 to V7R1 and need to roll back,
can I just slip the lic and the OS or do I have to do a full restore?


When an attempt is made to slip an older release over a newer-release, the LIC installation is supposed to halt with a SRC to prevent a back-level.

Presumably a SAVSTG is an option for any partition just as with a non-partitioned system.? Having such a saved image [in addition to the full system backups in case there is a media error on the image] is a nice option to have available, from which a reset\roll-back can be made to the saved installation's release\hardware to include all system and user data. That is, the /restore storage/ operation is much easier and faster than a scratch install of the LIC and OS followed by the *NONSYS restore. I believe in either case the first step initializes the disks so that no visibility of the newer-release installation remains; the latter case, for sure.
