A colleague of mine has done this about three years ago, moving from
AIX 4.3.3 to Solaris 2.7... if I'm remembering correctly, it was via
a DB backup-restore to flat file, with TSM 4.1.5.x.

I don't believe there were any hassles, apart from having to do some
performance tuning post migration. The AIX system had ESS, the Sun
has direct attached A5x000 fibre drives. The Sun box now uses raw
devices, and quite a few of them.

The same server is still running today, still Solaris 2.7, but TSM
5.1.x.x.

Yes, IBM warned us it is not a supported migration, and, as such,
is never guaranteed to work. YMMV. Good luck!

generally during DR you go back to like platforrms

ya know though... since the other box is a "new" server, give it a
try...

on like systems, I've performed tsm db backups to flat files, ftp'ed
them
over to a different tsm server, perormed a restore db and things ran
just
fine

can't say what luck you may or may not have in going across different
operating systems but it is worth a try...

I know this is in the FAQ, I read the FAQ, I don't
like the answer.  :)

Even if I let the backups slowly expire on the old
system, and do new ones to the new server...which
will be extremely difficult due to the number of
tape drives I have...I still have 15 TBs of HSM data
on a single node that must be moved.  Is the only way
to do this export/inport?

Why can't the database be dumped and loaded on a new
server?  Isn't that what happens for DR?  Why can't
I just pretend I am doing a DR to my new server and
leave the data there?  This must be a stupid idea
since it is not in the FAQ, but I don't see why at
the moment.

I am changing the type of platform....moving from
a Solaris system to a AIX system.

Thanks for any insights into this!
