Hi guys,

I hope you are all well and can assist.
We have a 2003 and 2008 server domain environment.
We wish to put a 2012 domain controller in this environment?
We just want to understand the impact of doing this in terms of:
1) What FSMO roles will this 2012 DC inherit or "take" away from existing DCs?
2) Can a 2012 DC exist seamlessly in this environment with no impact to existing services?
3) What things should we be aware of if any of doing this?

Any help greatly appreciated.

1.  It won't take any away but I'd transfer them to the new DC
2.  Yes, the schema update even happens for you when you promote the first 2012 DC.
3.  Main thing is that "dcpromo" has been killed off...try it.   There are good step by steps

I am assuming you know that you will need to run ADPREP to prep the forest and the domain for a 2012 DC.

Don't get afraid by its look
I have done setup in my env and It was errorless in my case ...Just make sure you follow steps given by Mkline71

And make sure your existing env is error free i.e dcdiag /q and repadmin /replsum are clean
DNS pointings are proper in your proposed 2012 DC

No I have not... 2012 is ugly =), try as I might I can not deal with Metro and personally I do not want to "hack" our image to get a start menu.  At this point I am crossing my fingers that 8.1 will bring back the start menu.

The upgrade is however the exact same process as going from 2000 to 2003 or from 2003 to 2008R2, both which I have done multiple times, most recently 2 months ago on a domain with 1000+ servers and 15k user accounts.  I'd be happy to answer any questions /  relieve any concerns you have.  It is actually a really simple process.  What OS are your current DCs?
