That sounds a like you would need this small hack to do the job:


  mv_conffile /etc/nsd3/nsd.conf /etc/nsd/nsd.conf 4.0.0~ nsd3 -- "$@" 0

Note the additional 0 at the end, that is needed to make
dpkg-maintscript-helper properly take over the conffile even on the
initial installation of nsd, otherwise it would skip the job ... it just
adds an "old version" in case "$@" does not contain one ...
