Nope.  Doing so would only add more steps where the person doing the
upgrade could potentially make mistakes.  :)

No problems.  As of today, you could upgrade from 0.14 to SVN trunk
without any special DB upgrade procedures--the upgrade would just be
done automatically as you start up mythtv-setup, mythbackend, or

1) catch up on all the release notes (
http://www.mythtv.org/wiki/index.php/Release_Notes_-_0.19 and
2) shut down mythfrontends, mtd's, mythjobqueues, mythbackends
3) upgrade mythtv, mythplugins, and myththemes on all hosts
4) run mythtv-setup on the master backend and adjust settings as desired
5) run mythbackend on the master backend
6) run mythfrontend on the master backend and adjust the settings as
desired, if appropriate (unless it's a dedicated backend that doesn't
run mythfrontend)
7) repeat steps 4 - 6 for all other hosts (fixing backend (mythtv-setup)
settings for mythbackends and mythjobqueues and frontend settings for
mythfrontends and mtd's)
