Since you have space for both the traditional volumes and the aggregates, could you just not migrate the volumes contents to the new volumes and start snapshotting there, and at the same time retain the old volumes for a period of time until you don't require the old snapshots anymore.
That's what we did, and we didn't _really_ have enough space. I had to downgrade the old traditional volume to raid4, _and_ run without hot spares. Oh, and turn off autosupport to NetApp until it was all over, so that it wouldn't keep automatically opening new support cases ... :-(
