You might bring over all of your old data and snaps, then clone that into a new
volume. Bring your recent stuff into the clone. Since the clone only updates
blocks that are different than the underlying snap, you may see a significant
storage savings.
Two clones could even be made - one for

Not exactly sure how to do what you're recommending -- are you suggesting I go
ahead with using rsync to bring in each snapshot, but to bring it into to a
clone of the old set of snapshots? Is there another way to bring my recent
stuff in to the clone?
If so, then as for the storage savings,
Ugh, yeah, I've learned by now that you always want at least that one snapshot
in common to keep the continuity in the dataset. Wouldn't I be able to
recreate effectively the same thing by rsync'ing over each snapshot one by one?
It may take a while, and I'd have to use the --inplace and

In my case, snapshot creation time and atime don't matter. I think rsync can
preserve mtime and ctime, though. I'll have to double check that.
I'd love to enable dedup. Trying to stay on stable releases of OpenSolaris
for whatever that's worth, and I can't seem to find a link to download
