Objet: Re: [ADSM-L] V6.1 to V6.3.3 Upgrade Question
Hi,
ok, there are two parts about this TSM db upgrade. One is the change in db
schema for TSM. If and when you start a newer TSM server version using an older
database, the schema automatically gets updated, TSM takes care of that and is
actually what TSM always does in case of an upgrade.
In the case of a 6.1 to 6.[23] upgrade, db2 also gets upgraded from 9.5 to 9.7.
Normally the installer performs an upgrade of the database format when you
upgrade on the same host. Now, I'm quite sure that once you've installed TSM on
your new host you'll be able to restore the TSM server database on that host,
but you wind up with both the old db2 format and the old schema. You'll then
need to start db2, but not the database and run 'db2 upgrade database ...',
check the db2 9.7 information center for the details. You then can safely start
TSM and TSM will take care of the rest as I said before.
Now, the big Question is.... will IBM support this? My guess is yes, because
this is what the installer does during an upgrade. It's a shame it's not quite
as well documented as could be, I do feel your upgrade path is quite a
legitimate one.
(btw, I've not quite tested this on windows... and you're going from 32bit to
64 bit at that....) Make backups (of course) before you begin and don't burn
your ships behind you before you've verified that the new TSM server works
after all of this.
