I agree !
I've moved environments all around and unless you can detatch the disks and
put them on the new environment and import the volume group (which would be
hard on NT :-/ )  You are best off in doing just that... clear the volumes,
delete them, then add in new ones in your new environment.   Sure if you
don't delete them in the old environment they won't be there in the new and
they won't come online but you might end up where I am and have volumes you
can't delete :-(

In case you have a lot of storage pool volumes, you can create macro's to do
update the  vols reado, do move data's (to clear cached files if need be),
and then delete the volumes... in your new environment you may also set up a
macro with all your new volumes to be assigned... this way if you are
pressed with time you just issue a macro and all is done !

I did this when I recently moved 5 tsm environments to new equipment in a
new location...
