John,

 If you create a new copy storage pool using the new STK device class you
can issue the 'Back storage command' to backup one storage pool to another.
That is how we migrated from IBM Magstar to STK 9840 devices.

Greetings,

We are trying to upgrade the tape media associated with a backup copy pool
from DLT to STK 9840 or 9940.

It appears that you cannot create a hierarchy within a copy pool, and do a
transparent migration from one copy pool to another.
It also appears that you cannot MOVE DATA from one copy storage pool to
another copy storage pool.

Has anyone attempted this kind of data migration, and if so how was it
accomplished with out having to recopy all of the data from the primary
storage pool to the copy storage pool?

Thanks to anyone for any input to this problem.
