Solaris 9 should be happy to upgrade with no intervention to SVM (such
as breaking mirrors) at all.

That's the first thing I tried when I got my paws on the first
pre-release Solaris 9 with SVM integrated - I set up a mirrored swap
and root configuration on Solaris 8/DiskSuite 4.2.1 and upgraded to
Solaris 9. I was very pleasantly surprised with the results.

Of course the usual caveats apply; YMMV, always take a backup first.
