Greetings, ADSM-L wizards!

We have just installed ADSM and a couple of 3590 tape drives.
When I set up ADSM originally, I turned colocation off.  I'd now like
to turn colocation ON to improve restore times.

I'd like to move the data off my existing volumes (not colocated) to
new scratch volumes (WITH colocation), then return the original
volumes to the scratch pool.

Has anyone done this?  What is the best method for doing this?

Thank you in advance.

David Wilshire
