We've got a web application product whose home page is at, for example, abcd.com
One of our clients is running the web application on a sub domain. E.g. customer.abcd.com
Both domains are currently hosted with Arvixe and Name Servers have been set for both sites.
I wish to move our primary site abcd.com to another hosting service. If I change the name servers on abcd.com, does it also affect name servers for customer.abcd.com ?
I need to know this for sure as I don't want to break our customers application.
