Hello Michael,

as we had enough room in our 3494 robot, we just added the new storage pools
as Magstar cartridges. So every migration from disc went suddenly to the new
magstar.
For the remaining 1000 x 3490E cart., after 30 days of expiration, we
started a manual move data back to disc pools. The data got then migrated to
magstar as normal backup data. These 3490e cartridges were about 20-30 %
utilized at the time of move data.

Hope everything doing well for you,

Rene
