Merge in the appropriate user & group entries from your backup into
/etc/passwd /etc/shadow and /etc/group (for user, password and group
information respectively).

Do not just overwrite the new files w/the backups.  You run the risk of
removing new system accts that may have been added in the new version
and are necessary for the correct functioninig of a program.
