Correct, that is what I am saying.

I believe that it is a good idea to change as few things as possible. 
Since the new MiniMyth contains OS related changes, I believe that it 
would be best to use the new MiniMyth built with MythTV 0.20 with your 
existing 0.20 setup. Once you are convinced that nothing is broken 
related to the MiniMyth OS changes, you can upgrade your setup to the 
new MiniMyth built with MythTV 0.21, which is the same as the new 
MiniMyth built with MythTV 0.20 except that MythTV has been upgraded to 
0.21.

And, of course, back up your DB before upgrading to MythTV 0.21.
