Practically all of that lives in /etc, which should not be large. Copy
all of /etc into your home directory before upgrading.
Consider what you've installed yourself: make a rule that it goes into
/usr/local or opt. You could make /opt a symlink to /usr/local/opt, and
/usr/local a separate filesystem: that way the installer doesn't need
to touch it.
Make a policy decision about where your system scripts go.
Make sure /var/spool/mqueue and /var/spool/mail (or equivalents) are
empty.
