I currently have a V4R5, and V5R3 systems. I would like to discontinue use of the V4R5, but I have several customers on that version, or lower, and they don't plan to upgrade. I'd like to move all the code/objects to the new system, but have found no way to do a savlib on the new system, and be able to restore to a system with V4R5 or lower. I have tried it, but no go. Any ideas on this would be appreciated.
