Exactly.
But in this case they've already done this the first time so instead of
redoing all that work they can just IPL to DST and start there, at step
14. Or, if they're comfortable with their change control they could
freeze changes on the Prod system, take the target system to a
restricted state and just restore of user data only, like Lucas
suggested earlier. As Chuck pointed out they would want to clear their
user data on the target system before restoring it.
Mike has a great opportunity here, as he can practice as much as he
needs to before he has to actually cutover and there's no reason for him
not to know exactly how much time it will take.
If I had the opportunity to do a side-by-side that's how I would do it,
practice until I was comfortable that the LIC and O/S were synced, then
do user data only for the final cutover. Especially since the PTF
install seems to be the main sticking point.

IOW, when doing the unload/reload then
Do steps 1 - 16 of Appendix D of
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/books/sc4153
04.pdf
with the 545 IBase CD. Then from there use the tape from the save?
Or are you talking restore the LIC and OS from an older save and then
restore the OS changes and your application data? How do you recommend
restoring the OS changes?

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 ?
Regards
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.
