We recently installed an  IBM3584 using LTO, our old 3575 libraries are using 
magstar, I moved two tapepools (about 350 tapes) from magstar to LTO using the 
mov data volume# stg=newstgpoolname, backed up the new tapepool, then deleted 
the tapecopy pool.   Then deleted the old stgpool. It does take some time, but 
it's better than trying to let the data expire. I just wanted to get rid of the 
old libraries ASAP.

Good luck... I tried this with the import/export commands, and it was
taking along time. The easiest way is to define the servers into the new
pool and let the other data expire on it own. It will take a while
depending on how much the data changes, but you will be there for a
while anyways to move all that data.
