Are you saying that the internal format of the db changes between OS's?
If not, I wonder if this would work:
Install ITSM on Solaris
Export filesystems on AIX containing db and log areas
NFS mount those filesystems to Solaris
Update dsmserv.dsk on Solaris to point to NFS db and log areas
Insights, ideas, gotcha's all welcome.

Subject: Re: Migration from AIX to Solaris
The big obstacle here is no, you can't move a TSM DB across platforms.
You can EXPORT the definitions, like policies, mgmt classes, schedules,
admins, etc. and reimport them to the new server; you can EXPORT and
IMPORT
the client data as well, but this is really rebuilding the DB on the new
server as the IMPORTS occur; and it's obviously time-consuming.
There are two ways to approach the move: some people just start backups
on
the new server, leave the old one around for a while until the data ages
enough to be useless, then shut it down. Other people try to do the
EXPORT/IMPORT thing. Your decision will depend on your circumstances, how
much time you have, and how much backup & archive data.
To do the EXPORT/IMPORT, you either have to have compatible media, or use
server-to-server virtual volumes to transmit the data from one TSM server
to
the other. (This requires a DRM license, I think for the target server.)
As far as using the same library, the answer is "probably". I don't
know
if you can share the 3583 with TSM library sharing, if so that would be
ideal as it would let you use the drives as needed. The other alternative
is to physically share the library and dedicate some drives to the new
server and some to the old server until you get all the data moved. Don't
know enough about the 3583 to get further than that.
That's hardly a complete answer, but maybe it will get you on the road to
the next set of questions....

Subject: Migration from AIX to Solaris
Hi everyone,
Currently we're running TSM 4.2.3.0 on AIX, attached to an IBM 3583
library. I'm curious about the prospects of migrating the TSM system
from AIX to Solaris.
1. Is it feasible to do this with the same library? (does the existing
data on the 3583 tapes need to be converted, or can a TSM database be
exported from AIX to Solaris, and the new server read from the existing
data?)
2. Is there a guide to doing this with the new versions of TSM? I recall
folks talking about an old ADSM Redbook, but I don't know if the same
rules apply to TSM.
I imagine this is a vast topic, so I'll start with these questions.
Thanks!
Doug
