Definitely backup the database, and you may want to choose a time when
the old backend isn't doing anything and shutdown mythbackend and
mysql initially. I have read threads where there were issues having
separate backends on the same network because of the auto discovery
features. I have seen people inadvertently connecting to or updating
the wrong backend or mysql database.
