First off all I hope I am in the right forum if not please forgive me.
I am moving my server setup from my home to a datacenter. No problem here (I hope).
I have at the moment setup my nameservers with dyndns so they are
ns1.mydyndns.org & ns2.mydydns.org.
Now with my new server I want to use my own primary nameserver as explained in this howto
So here finally my question: If I am going to chance the nameserver at dyndns to ns.mydomain.com wil I lose my connection for a wile or as I suspect and hoping will the site be reachable by the second nameserver witch is still ns2.mydyndns.org.
So basically what I am guessing is that as long I have one nameserver up and running I can chance the other one and keep the connection to the sites up.
