I do not believe this is true (if you are still on 0.21 or earlier
you need to perform special work due to removal of some
upgrade support for those versions), but it *is* a good idea
to read the 0.26 release notes, and the 0.27 release notes
in order to pick up actions you will need to (manually)
perform. In particular, you will need to add timezone
support to your mysql instance.
Basically, just follow the steps in the wiki at:

Gary is correct. You can go directly from 0.25 to 0.27.<br>
Always a good idea to backup everything first. Then stop the
frontend. It's probably best to stop the backend too, although the
upgrades scripts seem to do that for you if you didn't.<br>
<br>
If you originally installed from a Mythbuntu iso then you can use
Mythbuntu-Control-Centre to select the 0.27 repository. If, when
you then go to the "update manager" and select "install", it offers
you a "partial upgrade" or informs you that "packages are being held
back", you should decline and cancel out of the "update manager" and
open up a "terminal" session.<br>
<br>
At the command line do:<br>
sudo apt-get update<br>
and then do a simulation of the upgrade with:<br>
sudo apt-get -s dist-upgrade<br>
If everything looks ok from the simulation, go ahead and do the
upgrade for real with:<br>
sudo apt-get dist-upgrade<br>
after the upgrade is done start "mythtv backend setup" first. This
will update the database schema.<br>
When that's finished, start the frontend and it will update itself,
and that should do it.<br>
<br>
Some of the above procedure is outlined at the second to the last
bullet near the bottom of:<br>
<a class="moz-txt-link-freetext"

<br>
There is no need to add timezone support to mysql, as the Mythbuntu
upgrade scripts take care of that too. In my case it was all quite
painless.<br>
