"Simple" is in the mind of the beholder. Those of us who do this on a
somewhat frequent basis differ from those who rarely do it.
You may want to contract with someone to do it for you. I've done 6 lpars
this month. Some people on this list would call that a slow month.

What release are you upgrading to: 7.1 or 7.2?
If you are upgrading to 7.1 read the 7.1 Memo to Users.
If you are upgrading to 7.2 read BOTH the 7.1 Memo to Users and the 7.2
Memo to Users.

Follow the steps in the Knowledge center for upgrading your system very
closely!

Check out links recommended in both the MTU and Knowledge Center.
For example, you may read that a Power 6 can be upgraded to 7.2. This may
be true but ours couldn't because it had too many old cards, enclosures,
etc that were incompatible with 7.2. You really have to dig for these
finer details. We ended up migrating to Power 8's first.

Always helps to check with vendor supplied software to see if you have to
go to a newer version before you can upgrade your OS. For example, Domino
is tightly bound to the Java version on that OS and IBM has gotten into
the habit of dropping the lowest version of Java when they upgrade OS.

IBM sometimes comes out with new commands that may conflict with old ones.
RUNSQL is the one that most people are familiar with. But this is
covered in the MTU.

IBM sometimes comes out with new SQL keywords that may conflict. For
example RID conflicted with a column in a table in Infor. Wasn't really a
problem unless you recompiled the Infor program. That simply involved
wrapping their column name with double quotes.
