Hi.

I have a domain with functional level 2008 R2 and I want a new dc with 2012 R2.
I cannot find any information on whether 2008 R2 mode supports having 2012 R2 servers as dc or not.

I know adding a Windows Server 2012 R2 server as a domain controller in a 2008 R2 functional domain works, but is it supported?

All I found was this: http://technet.microsoft.com/en-us/library/cc771294.aspx

Yes it is supported, having a domain functional level of 2008 R2 means you can't have any DCS with an OS lower than 2008 R2 (2008/2003/2000) but you can have DCs with a higher level OS.

Thanks

As stated above 2012 DC is compatible with a 2008 R2 environment. When you add the new 2012 DC to the environment it does make Schema modifications to allow the DC's to communicate accordingly. This process is automatic when adding 2012 DC unlink previous versions where this needed to be done manually.

I think you are missing my question. It's regarding 2012 R2, not 2012.
And I can't find any documentation from Microsoft stating it is supported.

We used a support case with Microsoft, and they can confirm in writing that having a 2012 R2 DC in a 2008 R2 forest is infact supported. They apologized for the article not being updated and has flagged it as "in need of attension".
