Hi Andreas,

Don´t know if this is the best way to do, but it is working fine for me. We have old LTO-3 mixed with new LTO-5 tapes in the same pools (daily, weekly, monthly pools). I had to define the only drive twice in the director configurations for storage, one for media type LTO-3 and the other for LTO-5.  And I´m using old LTO-3 only for restores.

Best regards,
Ana

Hi all,

after an involuntary drive upgrade (old one died) from LTO-4 to LTO-5, I
wonder what the best way is to softly migrate our backup media to LTO-5.

I don't want to ditch all of our existing LTO-4 media and keep it in the
backup rotation, but I would be perfectly happy if future backups require
multiple LTO-4 volumes (we do have a changer). On the other hand, I don't
want to replace the LTO-4 volumes that are removed from the volume pool (for
off-site archival) with new (now deprecated) LTO-4 tapes, instead adding
LTO-5 media to allow future single-volume backups.

The easiest solution appears to be mixing both LTO-4 and LTO-5 volumes in a
single pool. Is that the best way to handle this situation? I am sure I am
not the only one migrating from one LTO generation to the next :-)

Many thanks,
  Andreas
