You need to read each and every one of Paul's links. Including the 7.2
Memo to Users even if you are skipping that. The reason being that some
things which die, or change drastically, with 7.2 aren't repeated in the
7.3 MTU.
Other links have been or will be suggested. Most of those are links that
will be included in the one's that Paul gave. Here's another one you will
get if you drill down far enough

Some of the trickier stuff is you will be directed to links to determine
if your particular Power server supports 7.2 and 7.3. The tricky part is
even if your server supports a higher release to ensure that you are not
running any cards and other devices which aren't supported. 7.2 was the
big one. Since you are going to 7.3 you will be better off. 7.2 had a
few models which would work but practically none of the cards would go.
7.3 did a better job of just killing off that whole model.
And it's always good to check with any vendor supplied software that you
have a version capable of running on a newer version of IBM i.
One big thing when reading the MTU is that when they say something do not
discard it as "they can't mean that, instead I choose to interpret it as
...". Feel free to double check with us on this list.
