Server 2012 R2 as DC in existing Forest SBS 2003 PDC

Last Modified: 2016-02-28
just want some feedback on this.

I am installing a new server with MS 2012 R2 Server Standard, and Exchange 2013.  Thinking about adding the Server as an additional DC in an existing Forest allowing the SBS 2003 server to continue as Primary Controller.  The existing SBS 2003 is the current Exchange server.

I'm thinking I will allow users to continue to authenticate through the SBS 2003, stop Exchange on that server after migration and then add each user's Exchange back to the new Exchange 2013 server.

The obvious short term benefit is to prevent from having to reconfigure each workstation/desktop/user to a new domain/server.
