I would backup the home directories, /etc/passwd, /etc/shadows and other 
config files, like for printer etc. Then I do a clean install and 
merge/replace the new config files with the old one. If you are using 
other authentication such as LDAP or NIS, you should save appropriate 
config files and restore them after a clean install.

I would just do the same here. Save all approriate config files etc and 
do a clean install and restore. You might consult the man page before 
you do restore of config files.
