You can export a node's data directly from one TSM server instance to
another one if you use the TOSERVER parameter in the EXPORT NODE command.

That being said, depending on your retention policies, it might be simpler
- and faster - to simply take the clients that back up to TSM server 1, and
point them at TSM server 2, and let the old data expire off of server 1 as
time passes. If you need to restore from the old TSM server, just point the
client back to server 1 for the restore. When all the data on server 1 is
older than your retention policy, it can be decommissioned. Archive data
should be copied to server 2, of course.

Hope that helps!

I'm sure someone has done this before. I'm just looking for a little
kick in the right direction.
I have two TSM servers.
One (TSM server 1) with a L700 library using SDLT320 drives with a 50gb
db and approximately 90 TB of data and another (TSM server 2) using a SL
T950 with LTO-4. Both are behind the same SVC.
I'm combining the two TSM servers into the same library and into the
same TSM DB.

Option one, get a LTO-4 drive connected to TSM server1 and export nodes
one at a time, then import the data into TSM server 2.

Option two, get a SDLT320 drive connected to TSM server 2, export from
TSM server 1 and import into 2.

??? Option three,  Is it possible to export to disk, and move the file
system from TSM server 1 to TSM server 2 and import ?

Option 1 and 2 will be time consuming, Option 3 would probably be the
most efficient, if possible.
Any advice or any other suggestions ?

Both TSM servers are running TSM 5.4.3 on AIX 5.3.

Thanks,
Duane
