Since the migration from Power5 and Power6 to Power7 leaves anything but SAS/Fibre attached devices behind, the likelyhood that you can get a good temporary test bed is very high. Yes you'll share tape devices and such for awhile, but even if it's more than that, a migration plan can be made to accomplish the migration or re-implementation with proper prior planning.

I agree with you Charles. But...

1 - If IBM publishes the 'migration' at
then that must be another officially supported path also.

2 - Not everyone has multi lpar or multi box environments to test.
Granted, this person will have a new system which could be an ideal test
environment. Perhaps we don't know all the details, like is the new
system really functional without taking some critical hardware out of the
old one and putting it into the new one?

Upgrade the v5r4 server to 7.1 save it, and restore to the new box. I personally would take advantage of the fact that you've got the second box there and would get it up and running ahead of time to do some testing. Then on cutover weekend, I'd restore the latest 7.1 save from the old box. I've done the above multiples times in my 16+ years on the platform. I have never, nor would I ever try to move from the v5r4 box directly to 7.1 without experienced help. At my current employer, we replaced 100+ v4r5 systems with v5r4 ones. But we paid IBM and and BP to come up with and implement the process. Even with experienced help, I wouldn't be willing to do this without testing the process and my applications on the new box first.
