The debconf answer part should be easy, just read the old answers and db_purge them after you've done that successfully. For the transition of conffiles, I think the way to go is to use ucf. ucf will give a configuration file dpkg-like conffile protection although they are not conffiles. - The new configuration files are shipped in /usr/share/openswan/ instead of their intended location in /etc; the old versions are registered in the md5sum files in the same directory - In preinst, you move/rename the existing conffiles - In postinst, you let ucf do the work (recognize the existing versions as known if they are unchanged and copy the new ones to their places, or show the user a diff if he has changed the conffiles).
