Last winter I tried to step from 8.10 to 9.10. Looking trough the 
changes, not only on myth but also on ubuntu itself, I decided it was 
time for a fresh install. I have to admit, the 8.10 installation was 
started 7.4 and made the steps inbetween.

Reasons for a fresh install did include the changes in myth, an update 
did not work, later I found it was possibly due to database changes.

The major ubuntu reason for a fresh install was the move from ext3 to 
ext4. Specially for myth recordings, this was welcome. However, if you 
previously already have chosen an alternate filesystem, then you might 
not need ext4 and/or a fresh install.

With an ubuntu update the ext3 filesystems can be updated to ext4, but 
that does not remove the problems, as upgraded ext3 filesystems are not 
fully converted, just enough to act as ext4, not to gain the advantages.

On the other hand I did have severe problems with the fresh install of 
8.10: analoge channel scanning did not work for example. And the data 
migration is something...

I started with the re-installation preparation untill the machine should 
go off: backup and configuration and such all prepared. Then I started 
with an upgrade, just to see if it works. Unfortunately, the myth 
database change (and my twiggling with it) ruined the database. I have 
to admit I screwed up more. Then I switched back to re-installation. I 
used about a weekend for the update.

So its up to you.
