We are in the final stages of migrating from 10 year old hardware running TSM 5.3.6 to new hardware running TSM 5.5.2. To accomplish this, we have been using "export node" to get the data to the new server. This has worked great for making the transition mostly seamless for the users and can be accomplished during the day while no backups are occurring.
We are now left with four nodes that have very large backup sets (800GB, 900GB, 2TB, and 4.5TB). Unfortunately these are all Oracle TDP backups, with transaction log backups happening every 4 hours. I tested doing an export of the 2TB one and it took 18 hours. I then issued the command again with FROMDate and FROMTime parameters for the past 18 hours worth of data. This resulted in creating additional filespaces for each of the databases (/Database was recreated as /Database1). This doesn't look good, so we didn't cut over.
Is anyone aware of a way to accomplish this migration, short of suspending the TDP processes during the migration? All data is housed on a Virtual Tape Library (EMC DL4200).
