This is because the installer itself does not seem to
provide an upgrading function explicitely, as seen (or
_not_ seen) in the "primary menu".

It seems to be the only option currently available,
even though it means that the task is not performed
by the installer, but instead via CLI.

The problem here is that a version upgrade 9.1 -> 9.2 might
involve adding, for example, users or groups the new version
requires, so paying attention to possible changes is a good
idea. Having files scheduled for alteration to a different
directory is a good idea, as well as having a backup of the
own (probably modified) configuration files. :-)
