1) With old MySQL and old Myth version: export the database to the
"portable" SQL format http://mythtv.org/docs/mythtv-HOWTO-23.html#ss23.5
2) Upgrade MySQL and Myth
3) With new MySQL, import the old database
4) Start mythtv-setup and let it update all your data to the new Myth

Anything else you do leaves you on your own with your (possibly corrupt)
manually "fixed" data.
