Hello,
My current scenario is, I have 1 DC running Windows Server 2003 R2 and i have recently purchased a brand new SBS 2011 server. When configuring SBS i elected not to use the migration option due to medical software running that is not compatible on SBS 2011 and i would need to keep the current DC on the domain but not running as the primary because SBS must be the primary. So i now have mydomain.com (2003 R2) and mydomain2.local (SBS 2011) on my network. How can i merge both into 1 if possible keeping both domain names? Can DNS be configured to point to both as its much easier for my users to type mydomain.com instead of mydomain.local. I've read that i can dcpromo the 2003 server and then add it to the mydomain.local domain but how would DNS be affected? will i have to manually recreate all DNS entries from the 2003 Server?? or is there an easier way?
