We currently run TSM V4.2.3.2 on AIX 4.3.3. We want to upgrade to the TSM

My feeling is upgrade AIX to 5.2 and then TSM.

We upgraded from TSM 5.1 on AIX 4.3 to TSM 5.2 on AIX 5.2.  Here's what we did:

1. Run 'cleanup backupgroups' first.  Not sure if that's on TSM 4.2 - I
think it came later, or there was a fixed version later.

2. Upgrade AIX to 5.2 (64bit in our case).  We uninstalled TSM 5.1 then
re-installed it with the AIX5 64-bit filesets.  No upgradedb needed yet.

3. The next weekend, we upgraded TSM:
   a. Hide your dsmserv.opt until you can upgrade to 5.2.2.
   b. Install TSM 5.2.0 from CD
   c. Upgrade to TSM 5.2.2
   d. Apply TSM 5.2.2.1
   e. unhide dsmserv.dsk, THEN run the upgradedb.
      There are performance improvements to the upgradedb in 5.2.2.
      If you don't hide your dsmserv.opt, the 5.2.0 install will run
      upgradedb slowly.  If your DB is small, it may not make a difference.
      Ours ran for quite awhile.

We chose to do the AIX upgrade separately from the TSM upgrade because we
had a limited downtime window, and we knew that the upgradedb would take
awhile to run on our database.

If you have a huge database, make sure you set your logmode to normal
before you shut down your TSM server.  Else you risk the log filling up
while the upgradedb runs, and it will fail.  We learned this one the
hard way.. :-(
