A general advice: be a pessimist and expect things go wrong after the 
upgrade. (Sorry David... ;-) Therefore back the old version up to be able 
to restrore it quickly just in case. The files to be backed up are:

/etc/init.d/mimedefang
/etc/mail/spamassassin
/etc/mail/mimedefang-filter
/usr/local/bin/mimedefang.pl
/usr/local/bin/mimedefang
/usr/local/bin/watch-mimedefang
/usr/local/bin/md-mx-ctrl
/usr/local/bin/mimedefang-multiplexor

Secondly, since you might have customized /etc/init.d/mimedefang and
/etc/mail/mimedefang-filter, do not compare these files with the ones in the
new distribution but compare the ones in the new distribution with their old
versions in the _original_ old distribution. Then update your customized old
versions *by hand* towards including the new features. That's the way I do
it since my (and probably everyone else's) mimedefang-filter is not so
easily comparable with the templates furnished in the MD tarball.
