Is a SAVE 21 sufficient for OS upgrade??

Hi gang. I posted earlier about going from V4R3 to V4R5. But I have one more question before I make the leap. JUST IN CASE, is doing a PRTSYSINF going to print all of the info I would need if something gets hosed during the upgrade? I plan to do 2 SAVE-21s before and after the upgrade, but I wanna cover all of my bases. Nelson

I recently did the exact task you have at hand. I did the PRTSYSINF and also did the Option 21 save. The upgrade went smooth and I did not need to do anything else.
