[mythtv-users] Migration issues from 0.20 to 0.22

I think my problem is that I'm trying to migrate too many aspects at once,
and I don't know what order to do it in. Here's the current setup.

Several year old installation of Ubuntu with Myth 0.20. SIngle machine
acting as the frontend and backend. Using a PVR-350. I'm running X over the
350's TV-out to my TV. The X part was very finicky to setup, so I don't
really want to mess with that machine any more than I have to.

I'd like to modernize my setup, and eventually retire that old box. My
desired setup is a single mythbackend running on my home server and several
front ends around the house.

 I have the server part all set up. I just installed Ubuntu 9.10 and myth
0.22, configured an HVR-1600 and that machine is working perfectly as a
front and back end.

I have also set up a second front end on a different ubuntu 9.10 machine,
communicating with the backend server, and everything works fine.

Now the part I can't figure out. How do I migrate all my data off the old
0.20 myth box to my new 0.22 backend?

The recording files were on an NFS server, so they are accessible to the new
backend. I've done a backup of my old database using mythconverg_backup.pl.
But I'm stuck now. I only want to restore the recording data, I don't want
to do a full database restore (since user names and plugins are different),
but the partial restore option says it only works with identical DB schemas,
and I assume the schema changed from 0.20 to 0.22

Can anyone help me over this last hump?
