There's several ways you could do this migration, but the way I would do it
is:

1. upgrade the old server to TSM 5.3, after backing up the DB of course.  I
wouldn't bother putting the ISC on the old box at this time, it's not needed
to get TSM up to 5.3.  Note - The last upgrade of TSM from 5.1 to 5.3 on AIX
I performed took upwards of 8 hours for a 40GB database - lots of database
changes that it needs to deal with between 5.1 and 5.3.

2. Export the database

3. install 5.3 (and the ISC) on the new server and import the database.
You could do a DB backup/restore, but the export/import will give you a
nicer, cleaner, friendlier database at the end of the day.

You could move to the new server on 5.1 and *then* upgrade TSM to 5.3
afterwards, but then you have the whole ugliness of unistalling/installing
new code, etc.   Personally, I like doing it as clean on the new server as
possible....

later,

Paul

Subject: [ADSM-L] Upgrade 5.1 to 5.3 on new server

Hi,

we're running TSM 5.1 on AIX 5.1. We bought a new server
with AIX 5.3 where we want to install TSM 5.3. What is the
best way to migrate the data to the new server?
Would it be possible to import the 5.1 database and
server export files into the new server? Or do we
first have to upgrade the old server to TSM 5.3,
backup the database and then restore it to the new
server?
