Yes, it's ugly.
Yes, as far as I know, exporting all the client data is the only supported
method.
Yes, it's a HECK of a lot of work.
Yes, it takes your 2000 tapes, creates 2000 portable tapes, which get
imported to create 2000 tapes.
I forget which version of TSM you are running; starting in 5.1, you can
export directly to from one server to another.
You set up a server-to-server definition, and transmit the data rather than
using sequential media.
(And that may actually be slower than creating the export tapes.)
I've done it with sequential media, and with server-to-server (I was going
AIX to Windoze).
Neither is pleasant.
My recommendation:
Just export/import your archives, and any old filespaces that are not
replaceable.
Point the clients to the new server, and let them start fresh with backups.
Keep the old server around for n months; if the clients need to restore
older data, they can always point their dsm.opt back to the old server for
restoring for n months.
I will probably take you n months to do all the import/exports, anyway :>(
If you find a better way, I would love to hear about it!

Subject: Moving TSM from one platform to another
Is it possible to move from MVS to AIX without having to export all client
node data so long are your storage device is the same on both environments?
i.e. if my current environment has 2000 tapes full of client data, and I
want to move my environment from MVS to AIX, do I essentially have to export
2000 tapes, create 2000 new tapes, and import those 2000 new tapes to my AIX
environment to read the client data (thus creating another 2000 tapes)? Or
would the present 2000 tapes be readable from the AIX environment as long as
I export the server without the filedata and import it into the AIX
environment (and have the same type of device connected to the AIX server of
course)? In other words I'm trying to gauge how much work it is to move TSM
from one platform to another..
If I remember correctly it's ugly and you do have to export all the client
data as well..
