Section A: Move the DNS Workload to Windows Essential Business Server
This migration assumes that you have one existing DNS server that is not integrated with AD DS. If you have multiple non-integrated DNS servers, look in the properties of your domain’s forward zone to determine which DNS server is the primary server. Perform the steps that refer to your existing DNS server on this primary server.
If you are unsure how to determine whether an existing DNS server is the primary server for your domain, continue with the following steps, and they will help you determine which server is the primary.
Section A includes topics about how to accomplish the following procedures:
