I have a customer with a SBS 2008 server. The customer has approved an upgrade to Windows 2012 R2 with Exchange 2016 OR Windows 2016 with Exchange 2016. The goal would be to add the 2nd/new DC to the network and then, remove the SBS 2008 server.
I'm seeking recommendations on how to remove the SBS 2008 server while making the new Windows server the primary DC.
Unlike Standard Windows Server (2008/2012/2016), can SBS 2008 be demoted using DCPromo?
