[ADSM-L] Moving to a new library (and ending up with old names)

Hi *SM-ers!
We are using virtual libraries (EMC DL-series) in our TSM environment
and we will migrate to a new model soon.
I would like to do this without ending up with new names (stgpool,
devclass, library names) in TSM.
Storagepools can be renamed, so I rename the old pool and give the new
one the previous name of the old one, so no problem here.
The old library (library and drive definitions and paths) can be removed
and recreated by using a different name, which allows me to use the old
name for the new library. Again, no problem here.
The problem is the deviceclass. You cannot rename a deviceclass, nor can
you update a storagepool to use a different deviceclass(name). I cannot
think of a way to move to a new library and keep the old deviceclass
name.
Am I overlooking something here or is this just not possible and do I
have to accept a new deviceclass name after the migration?
Thank you very much for you reply in advance!!!
Kindest regards,
Eric van Loon
