I'm assuming i can use <a href="https://kb.isc.org/docs/managing-manual-multi-master" rel="nofollow" target="_blank">https://kb.isc.org/docs/managing-manual-multi-master</a> to "demote" one of them but is there anything to look for concerning possible inconsistencies and how do I check for those issues? Thanks for any insight.</div></div></body></html>
