We are still at 5.1.6.1, next upgrade scheduled for 2Q04, so I guess I will
have it then. I could use it to accomplish this migration, but I think it
would be lengthy process, considering I can probably move around 1 - 2 TB
daily.
The idea of moving off of OS/390 is because we are taking too much CPU and
weekly IPLs. So we want to dismantle those virtual servers and not leave them
around. So leaving them up just for restores is not workable. Also it would
get very confusing for our 90 member helpdesk, hard to make them understand
when all they do is restores using a GUI.
Unfortunately, archives are the least of worries, we don't do many of those.
We strictly do daily incremental backups with retentions anywhere from a few
days to FOREVER, yes, some wise lawyers here thought it was necessary to keep
data forever against our recommendations. The TDP stuff here is mainly
Exchange and with only 8 day retentions, we can just move those and start over,
but that is only a fraction of the data.
I imagine we will do this as I planned, a 2 - 3 year project where we will
create new TSM servers and put all new nodes there and migrate old ones as we
can, deleting some backups along the way when they are obsolete, it just means
we have to share the ATLs between the 2 different platforms for that time,
maybe not the most efficient, but workable.
Thanks!

Ryan,
IBM does have incremental server to server export at the 5202 server level. It
came in
below that but I am not sure where. Of course you can only use it after you
have exported the
current 270T, which is a long time from now.
Just because you do backups to a new server, you don't have to lose access to
the
backups/archives on the old server. Each client can make stanzas or shortcuts
that
override the default serveraddress and/or port number.
The TDP products may be more difficult to do than plain UNIX or windows clients.
After the retextra & retonly times
have passed, you can delete the backups from the old server. You then need to
export the
archives.
Good luck,
Bill
