This is not difficult.

1. Make sure that new data can be written to LTO3, via migration,
reclamation, DB Backup, etc. This must work, first.

2. Mark all the LTO2 tapes readonly.

3. Remove all LTO2 scratch tapes, and remove new ones as they are freed.
You might need these library slots to accomodate new LTO3 tapes anyway.

4. Now expiration, migration, and reclamation will start to do the job
for you, but that likely won't be fast enough. Help the process with
MOVE DATA.

A more complicated approach involves separate storage pools for the
different tape types. We're now doing this to move from SDLT to LTO4.
I've set the Reclamation Storage Pool for SDLT to be the LTO4 pool. Now
all I need to do to propel the process is to reduce the reclamation
threshold in the SDLT pool by 1-2 points every day.

to move all data from.  Both LTO3 drives and LTO2 drives are still
installed and usable.
