Then your problem may be unrelated to the move of one file from a
package to another, but instead related to dpkg being unable to
replace a directory by a symlink. In a 'standard' such upgrade (with
only one package), the new symlink is ignored (not installed). With
your conflict/replace, it seems it leads to a dpkg error.
  I hit this problem with one of my package (#362487).
Here is the hack I used to get arround this bug in the postinst of my
package :
case "$1" in
       # Workaround a dpkg bug (transition directory->symlink does not work)
       if [ -d /usr/lib/python2.3/site-packages/mercurial \
            -a ! -L $DESTDIR ] ; then
               # DESTDIR is not a symlink as it should be
               if rmdir $DESTDIR ; then :
                       # DESTDIR is not an empty directory !
                       # We try to move files
                       mv -v $DESTDIR/* /usr/share/mercurial/templates/
                       # and we fail is that still does not work
                       rmdir $DESTDIR
               ln -s ../../../../share/mercurial/templates $DESTDIR

Perhaps you will need something similar (and perhaps in the preinst for
