during updates within the same version like from 5.x to 5.y you don
need to upgrade the theme and can leave it as it is. But in some cases
there are theme updates available even for the same version, in that
case one has to follow the same procedure as for a module.

But when you are upgrading from one version to a higher version, like
say 5.x to 6.x , then first you upgrade the installation to the latest
release in 5.x and then set the theme to a basic theme like chameleon
or something and disable all the contrib modules. Then upgrade the
core installation to 6.x and if this goes on smoothly , update the
contrib modules to their corresponding 6.x versions , and after that
finally you can replace the theme by its 6.x version and change the
theme back to the original theme from the basic theme which we set in
the above process.

In short , the theme behaves more or less like a module, and hence the
upgrade process is also similar, apart for some minor caveats.
