I have an issue, I am trying to migrate a sharepoint 2010 to 2013. From the Microsoft documentation I understand I am to replicate all the 2010 settings including url and port number. My 2013 sharepoint farm is installed on a virtual server(Has the company's internet site runnig on it). I will like to know the following
Do I need to configure a dns server to use host headers(in order to replicate the 2010 url).
How can I setup dns server without affecting my already created web application on the 2013 farm.
