Oh lordy be! You really know how to ask for trouble! I hope your resume
is updated.

I would STRONGLY recommend NOT changing everything at the same time. If
something goes wrong, as it inevitably will, you'll never know where to
start looking for the problem. (Or, are you being given a week of
downtime for this?)

Break this into 3 separate projects:

1. Move to new hardware, keeping everything else the same.

2. Upgrade AIX from 4.3.3 to the latest 5.2 (with Maintenance Level 3!)

3. Upgrade TSM from 5.1.6.1 to 5.2.2.0

Steps 1 and 2 could be swapped and done in either order. But the
important thing here is you should approach this as three separate
projects. If something goes wrong at any of the three steps, you'll have
a much easier time figuring it out and recovering, in a reasonable
amount of time, and with reasonable chances of not destroying your TSM
database.
