Ok, this is a bit off topic,
but I have been asked recently how to migrate data on tapes from
TSM to NetWorker (or NetBackup to TSM or the like).
And I haven't found an easy answer yet.
My theoretical migration scheme would be like this <very first guess>:
1.) have a very big disk (SATA array) at hand
2.) develop a new systematic order for the migrated data sets
e.g. $clientname_$savetime
3.) create directories/volumes named according to this order
4.) restore datasets into this directory with $OldTool
5.) backup directories/volumes with $NewTool
While this could(?) be a solution for filesystems,
I expect a lot trouble for all those application data
(i.e. R/3, Oracle, Exchange, etc.), which will not
fit easily into a directory scheme like this.
And most of the restores would require the application on
the "migration client".
Sure I know I could keep the old servers/tapes/drives/licenses etc.
Maybe some else has a better idea, but if this were me, I would set
aside a server that has whatever is needed (e.g., Windows SQL,
Oracle, SAP, Novell, etc.) to recover any type of data that might
need to be recovered. The biggest fly in the ointment is licensing
for the software you might need such as Oracle.
