Hi,

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

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?
q2. When I add the 2012 R2 domain controller how do I tell it you work with 2008 domain functional level?

I don't have test system so I'm bit nervous doing this on the production before I get the correct knowledge.

Thank you.
