Here's another ugh:
We converted 2 AIX TSM servers to Windows TSM servers, total about 150
clients, < 5 TB.
For the first one, I moved the backup data (via server to server
export/import). It was so time-consuming that for the other, we just moved
archives and started backups fresh.
But the other thing we ran into was that the password has to be reset on the
client end, even though the nodes were created/registered on the new server
via export/import. Something about the way the password is encrypted. Not
sure what it means in your case, but that was actually the worst part of the
logistics for us, as clients are scattered all over.

Bill,
Thanks for the info. It looks like we may have an interesting time ahead for
us. If ex/import is the only way to go I'm not sure if even the incremental
ex/import feature, if IBM ever comes out with it, will help us. Leaving the
data behind is not feasible, we need to have 24 hour access to it at all
times. We currently have 3 3494 ATL's with a combined total of around
14,000 media 3 and 4 tapes. That would all be converted to the UNIX
platform, it would be nice if the new media manager could see the tapes and
recognize them as the same. I may have to see if IBM could look into making
that work....
Thanks!
Ryan

We didn't move any backups, we did fresh backups
but I will move archives using the server to server export
feature in 5.??.
The old server had just 20T of data.
Our tapes, 9840's, were not managed by ca1 or any other tape mgmt software.
I defined tapes
explicitly to tsm. We are a small organization, which is why the mainframe
is on the way out
not only for tsm but for everything.
You may be able to reuse the media, but you can't transport the backup data
from server to
server. You will need to do fresh backups or exports & imports.
The library on mvs is an stk silo, on solaris it is and stk l700e managed by
tsm.

fear is having to convert or move 270 TB of data already on tape. Or did
you not move any data from the OS/390 side and just start with fresh
backups?
