My company is looking into leasing the new 520 Power5+ that was recently announced. I have been looking into the OS level I need to be at in order to run on it. Currently, we have and 825 w/processor feature 2473 and are at V5R3M0 cum 05207.
At first I read that the Power5+ will run on V5R3M0, but I have been hearing some conflicting reports that we should be at V5R3M5. The I_BASE for V5R3M0 I have installed is RSC, should we be higher? Do we have to be at V5R3M5?
Usually I would upgrade my current system to the OS level that the new machine requires, but I?m finding IBM can?t give me a clear answer. My goal is to do a little as possible to the operating system on my current system but be able to move my data and other licensed products to the new system. I would love to keep V5R3M0 as the base (V5R4 is too new) but do I need a more current base level I_BASE code.
