<p>First, you create <a href="http://MOMO.COM" target="_blank">MOMO.COM</a> on route53, with identical zone
contents.<br>
</p>
<p>Then you change the registrar to point to route53's nameservers.</p>
<p>Then you wait for at least 48 hours. At this point, no queries
for *.<a href="http://MOMO.COM" target="_blank">MOMO.COM</a> (including <a href="http://NS1.MOMO.COM/NS2.MOMO.COM" target="_blank">NS1.MOMO.COM/NS2.MOMO.COM</a>) should be
arriving at your nameservers.</p>
<p>Then you could delete <a href="http://MOMO.COM" target="_blank">MOMO.COM</a> from our own nameservers if you
wish - or you can just leave it there, it doesn't matter.<br>
</p>
<p>At this point, any other domains which use NS1/<a href="http://2.MOMO.COM" target="_blank">2.MOMO.COM</a> will
still be working as before. They will still be delegated to
NS1/<a href="http://2.MOMO.COM" target="_blank">2.MOMO.COM</a>. DNS lookups to resolve NS1/<a href="http://2.MOMO.COM" target="_blank">2.MOMO.COM</a> to A/AAAA
records will still work - those lookups will be querying route53's
nameservers. But the actual queries for those other domains will
still arrive at NS1/<a href="http://2.MOMO.COM" target="_blank">2.MOMO.COM</a></p>
<p>The important thing is: when you create the <a href="http://MOMO.COM" target="_blank">MOMO.COM</a> domain on
route53, don't change the contents. Most importantly, leave
NS1/<a href="http://2.MOMO.COM" target="_blank">2.MOMO.COM</a> pointing to your existing powerDNS servers - since
your other domains depend on being able to resolve NS1/<a href="http://2.MOMO.COM" target="_blank">2.MOMO.COM</a>.<br>
