I agree. I've done several of these. We try to keep our OS's current
just to avoid such dillimmas. Closest issue we had was migrating a 5.4
system on a 270 to Power 6. We upgraded the 270 to 5.4.5 first. Did the
straight migration over to the Power 6 and quickly upgraded that to 6.1.
Since then we scratched that system, started it with a new lpar and the
old one was restored as a guested lpar. Since that all were upgraded to
7.1.

I don't think any Power 7's support 5.4.5 like the Power 6's did.

Jack,

To get the most complete cut over you would follow the steps you
suggest, upgrade to V6 (or better yet V7 to get the most out of your new
hardware), then save/restore onto the new box. It will test your
recovery knowledge at the very least.

If you want to re-implement your applications on your new box, the load
up V7 with all the licensed programs, apply PTFs and then migrate the
applications. The problem with this approach is if there are user
objects in QGPL and QUSRSYS that need to be brought over. You'll have
to identify those objects and restore them manually. RSTOBJ with the
*NEW has worked for me in the past.

The other problem I have run into with this method is if logical files
are located in a different library that gets restored prior to the
physicals. I've seen as many as five restore passes needed to get all
the dependent files down. That may pop up with the unload reload as
well, but your odds are better there. To get past this I'll restore
the libraries with only the physical files, then come back and do the
logical files and indexes. Again very intensive.

I would prefer the first method simply because it's the safest.

Power6 on 5.4.5 to Power7 from factory FC0205.


Believe the easy thing to do would be upgrade power6 box to 6.1 or 7.1

then

21 save, 01d on the new box.

What if I want to port over only the data portion of the power6 box from
5.4.5 with a prebuilt power7 box, looking for steps involved in this. I

am

seeing varying results in my testing.
