I think most of us have our own list of what to do at this point and several of the ones you find in the forums are outdated. I do my updates more or less "unconsciously" now and is also very much specific for my infrastructure so I won´t share my specific steps.
Writing up something like this "officially" and having it as part of the user guide wiki would be a good thing though and nice to have so is a kind of "feature request" I guess. Automatic upgrades is still the holy grail of course and hopefully comes at some point.
