Yup, I had understood that.  We only have about 10 active volumes so
it was easy enough in my case to copy and paste the ids/uuids around
for mysql updates and lvrenames.  So I can now attach both old and new
volumes at my site.

I tripped over a couple more steps that I didn't know about but
managed to discover on my own as well, like 'cinder-manage db sync' to
set up the tables in the cinder database, which I'm sure are so
obvious as to be nearly invisible to people working on the code and
enough like any other openstack service it wasn't too hard to guess.
I collected up my notes and expanded migration section of the release
notes by a few steps
