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.

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.
