this has been considered best practice for quite a while, but is not 
really the case anymore (although old habits my take their time to die)

It is still OK to do it one step at a time, and it may help to track 
down a non-backwards-compatible change that your applications can't
cope with by doing it this way, and running application tests on each
major version step on the way.

From the server side itself there's no real reason to not just upgrade
to the final target version right away anymore. In the past such 
scenarios were not tested, but sometimes people would do it anyway
(intentionally or via a distro upgrade) and there were no related
problems related for several years.

So it seemed to be safe to skip over major releases after all, and we
also added test coverage for this in recent years.

So "like everybody else does" was never true to begin with, even though
documentation recommended to to it this way until some two years ago or
so. But by now it is not even really what the documentation suggests
anymore.

I was originally reluctant about this change in recommendation, but have
been convinced since and so far have not seen any problem with such
direct version skipping upgrades either.
