I have done some searches on how to go about doing an upgrade but I haven't found anything.  I figured I must be missing something.  Is there a guide for how to upgrade a mythtv backend?

The first, and most important thing, you should do when upgrading MythTV 
is create a backup of your database as a "just in case".  Do so as 
described at:

http://www.mythtv.org/wiki/Database_Backup_and_Restore

Then, just get the new version of MythTV installed (I'll let you/others 
figure out how to do that with Mythbuntu repositories), and (ideally) 
start up mythtv-setup to upgrade the database.  (The master backend will 
also upgrade the database for you, but using mythtv-setup, you'll get 
popups and notifications that you'll actually see, and it allows you to 
check to see if you need to change any backend configuration before 
startup--though you're unlikely to have much, if any, changes to backend 
configuration between 0.25 and 0.26.)

Note, too, that when you start up mythfrontend for the first time after 
the upgrade, each plugin will check its database schema version and will 
perform database upgrades for itself (so even after the backend upgrades 
the database, you will still see database upgrades when you start 
mythfrontend).

And, most importantly, there's nothing specific you need to do to 
upgrade the database or "migrate" the data or recordings.  Just have 
your full database in place and let MythTV take care of it for you.  
(And please do not follow the instructions on the "easy steps" page that 
Google tells you to read if you search for "migrating mythtv 
<whatever>"--it's wrong and will corrupt data.)
