fwiw the debian upgrade guide recommends

"The main things you'll want to back up are the contents of /etc,
/var/lib/dpkg, /var/lib/aptitude/pkgstates and the output of
dpkg --get-selections "*" (the quotes are important)."

--get-selections is nice because you can later pipe that list of packages
back at --set-selections and have it install all the packages back that
were there before in one go.
