Re: V5r4 Upgrade

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

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.
