Out of curiosity, which change are you looking for?  Is it one on master 
that's not in -fixes?  If so, there were a couple of fixes I've 
considered backporting, but haven't decided it's worthwhile, yet.  If 
someone was looking for one of them, though...

Or is this a fix that went into -fixes?  If so, aren't there updated 
RPMs available that pull from 0.24-fixes?  Which distro are you on?

There's a /very/ high level description  of getting the code at 
http://code.mythtv.org/trac/ (where you probably want "Stable: If you'd 
like to get the 0.24 stable branch, do this:").

Besides that, your above list of steps seems pretty much correct--though 
if you're using the same system, you probably won't need to restore the 
database (no sense replacing it with a copy of itself).  If you're going 
to new hardware, see http://www.mythtv.org/wiki/Backend_migration .
