Your scenario ought to work flawlessly.
As a precaution you can drain your disk pool(s) and take a DB backup.

        Subject:        TSM from AIX 4.3.3 to AIX 5.2


I am planning to 'migrate' a TSM server from an F40 running AIX 4.3.3
to a p615 running AIX 5.2.0.

We are running TSM version 5.1.8.0 .
This has been installed on the new machine.

I was intending to physically re-attach the disks and tape library
to the new machine. The TSM data is all in TSM specific volume groups,
so I plan to exportvg and importvg these.

I would then copy across the dsmserv.dsk and dsmserv.opt files to
the new machine, add tape & library devices again and hopefully
restart TSM on the new machine.

Does this sound like it should work or have I forgotten anything ?

The new machine is running in 64 bit mode so the code base won't be
exactly the same - but I can't see that this should make any
difference. Am I correct in this assumption ?
