There is no such list of issues.

You should consult the docs:

OS migration

This is the relevant part of the AIX 7 Infocenter:

Here are two nice articles from IBM Systems Magazine on that topic:

Hardware migration

This is from the Power Systems Infocenter:

Do an alt_disk_install to avoid lots of them. Some older hardware can't be upgraded past 5.3 and therefore not officially supported, and I believe SSA enclosures are not supported by 6.* and up.

From the topics tagged I'm assuming you're looking at migrating from AIX to some flavour of Linux, rather than performing some AIX version X -> version Y upgrade (you haven't indicated). If this is the case then you're best to think of it as a fresh start, as the directory trees, architecture, packaging systems, admin tools and supplied libraries are all different. In addition the command line utilities and/or arguments are different (unless you've been using the GNU tools rather than IBM's), for a very rough idea grab yourself a copy of: "Unix, Linux, and BSD Command Line Cross Reference" by N. Marsh.
