Just install 12.04, upgrade it to 0.26-fixes, shut all MythTV 
applications down, and then restore the (full backup of the) 0.23.5 
database to replace whatever initial database the Ubuntu package gave 
you ( http://www.mythtv.org/wiki/Database_Backup_and_Restore ), 
then...read the rest...

You can create the backup of the old database with:

I, personally, think that localhost should never be used in any MythTV 
setup--because it necessarily means you can never add any additional 
backend, frontend, client (MythWeb or 3rd-party) hosts of any kind 
(without changing the hostname/IP information).  So, I would recommend 
you do change the hostname (and IP address!) to something appropriate.

That means that after you restore the backup--and *before* you run /any/ 
MythTV application--you would need to do:
http://www.mythtv.org/wiki/Database_Backup_and_Restore#Change_the_hostname_of_a_MythTV_frontend_or_backend
and once that completes, you can run mythtv-setup to a) upgrade the 
database from 0.23.5 to 0.26 schema and b) allow you to manually change 
the "this server" and "master server" IP address settings to real, 
routable addresses.

As long as you have that full backup of the current system, you won't 
lose everything.  At most, you'll lose things you do after the backup 
was made (if you end up realizing later that the system is broken and 
it's easier to go back to the backup than to fix the issues with the 
broken/upgraded system).
