But V5R4M5 is just the LIC, your O/S remains V5R4. You have nothing to
gain by reloading the LIC and reapplying ALL the MF PTFs for your
cutover.

Thanks for all the replies.
The current system is V5R4M0. New box is V5R4M5 (has to be for power 6).
Going to V5R4M5 on the current and applying PFTs there would not save
any down time since we would need to take the system down to do that.
The BP was putting on the cumulative and all groups all at one time.
Said that had to be done because the restore process will only bring
over the PFTs for V5R4M0 and not those for V5R4M5. I was also surprised
it took that long for all the PFTs to go on considering the V5R4M0
system was current as of August.

Hi Mike
Did the BP actually just do a restore or did they do a mixed release
migration ? Your description of the process seems to have some gaps to
me which might explain why the BP wants to go this route.
What release are you currently on ?

Evan Harris

Subject: side-by-side upgrade
We purchased a new power 6 system as an upgrade and are able to run both
the old and new systems side by side. Our BP installed V5R4M5 on the new
system and then we did a full save (option 21) on the current system and
a full restore to the new. They the BP installed the most recent PFTs.
Total time to backup was about 4 hours, total time to restore was about
4 hours. Adding in the PFTs added another 6. 14 hours total downtime to
make the switch. We are going to check out the new system to be sure
everything is there and running and looks good and then schedule a
weekend to make the final cutover. Since the only thing that is going
to change is our data could we safely do a save (option 21) and then
just restore userprofiles and our libraries? BP would like to blow away
everything and start from installing
V5R4M5 again, then a full restore and all the PFTs again. Looking to
save that extra 6 hours of downtime.
