hi,

im doing dns migration from one set of servers to other set of servers.

dns takes about 24 hrs for TLDs(com. etc) zones and about 48 to 72 hrs for gTLDs(co.uk etc.). to avoid any kind of outage during this time - can I leave both servers as authoratative servers? will it avoid any kinda outage?

Hi,

If I understand your question accuratly then the answer is yes.  As long as the cached records will resolve you should have no issue. Once expired you can safely decomission the original set of nameservers.
