another DNS migration question - moved DNS but still shows old as primary?

Question

so I waited until I saw the router 53 servers showing as DNS for one of my least important domains, and then removed dyndns\oracle from DNS at the host level.
but - for Primary DNS and responsible email it still shows dydns.  is there another place I need to change that, or did I miss a step somewhere?

SOA
TTL
21600
Primary NS
ns1.mydyndns.org.
Responsible Email
zone-admin.dyndns.com.

Answer

What is the domain name in question?

In general, if you have a TLD (top level domain) registered with a Registrar A, have it hosted with a DNS Hosting Provider B, and then create a new hosted zone for the same TLD with a DNS Hosting Provider C, with the intention to use this new hosted zone, you need to:

a) Update A, with nameservers for your hosted zone provided by C
b) Wait for upto 48 hours before deleting hosted zone in B

On Linux, you can verify this by running whois  and it should display the namservers for the TLD provided to the registrar. These should match the ones provided by C.
