Hi all,

I'm about to commission 2x new Windows Server 2012 R2 and promote it as AD integrated DNS with Domain Controller (GC) role to replace the existing 2008 R2 DC/GC & DNS role.

What are the steps to implement it without outage or downtime to the existing environment ?

How can I decommission the old 2008 R2 Domain controller without impacting the Exchange email and DNS resolution ?
