I don't believe it is possible.
However, a clean install can be made as much like an old install if you want.
Use dpkg to get the list of packages (look at dpkg --get-selections)
Backup your /etc, your /var and /home. (Ideally you'd have /home on
it's own partition.
Probably also use debconf to spit out it's config details for
installed packages as well.

Then do clean install, restore package list, (restore debconf config
first), compare differences between /etc/ and your /etc/ backup.
Restore /var bits that you need.
