Thanks mate. this is very useful. <br />
<br />
the new DC with 2012 is going to be a child domain. I will follow the same steps as creating a new 2012 domain right?

Hi,<br />
<br />
We have 7 domain controllers with 2008 domain functional level and 2003 forest functional level. I like to change the forest functional level to 2008. Also I want to add a child domain with a 2012 R2 domain controller<br />
<br />
q1. Do I have to raise the forest functional level in all domain controllers or if I change it in the primary one will it replicate to others?<br />
q2. When I add the 2012 R2 domain controller how do I tell it you work with 2008 domain functional level?<br />
<br />
I don't have test system so I'm bit nervous doing this on the production before I get the correct knowledge.<br />
<br />
Thank you.

Child Domain, Forest and Domain Functional Levels
