If the ability to "re-implement" your software, meaning move it from an
older box to a new box presents itself, I will most often make that
choice for the very reasons Kirk points out. You can really clean up a
system. Also. you now have the ability to move custom work management,
communications, and configuration objects into a library of your choice
not QGPL, or QUSRSYS. You leave old objects no longer needed behind.
Once the new box has the OS loaded, user profiles, communications, work
management set up, ect. without the applications and data on it, you can
take a base back up. Take this opportunity to create your own install
media. Now if you ever rebuild the system use your own install media
and most of that will be preset for you! Really neat if you need to
build additional LPARs!
There are real advantages to the what Kirk suggests if you stop and
think of them. The downside, more work initially and a requirement for
stronger administration skills. The payoff in the end is much higher
than the cost in my experience.

Plan, Plan and More Planning as the others have basically said. Verify with
your Vendors that their apps are 7.1 compliant and run the Anzobjcnv
process until it is clean or you completely understand what will or won't
convert to 7.1 and if it won't, can you abandon that program/app or do you
need to replace / upgrade it either before or just after the upgrade.
Upgrading the Old system to 7.1 has its risks, but they are manageable.
Leaving the 5.4 box alone and moving everything to the 7.1 also needs very
careful plan and care so you don't down level OS objects in places like
QGPL, QUSRSYS etec as well as the IFS. 2 advantages I see of 'moving
things' to the new box and not up grading. #1 Great time to Clean House and
leave crap behind you don't need any more. #2 You be able to get to the
point of refreshing your data files to go live, This should be much shorter
downtime in theory than Upgrade to 7.1 and then later Save/Restore 21 to
move the the new box.
