Our current Lync environment consists of 3x Lync 2010 servers and Windows Server 2008 R2 SP1 domain controllers.
Where do we stand on upgrading the domain controllers to Windows Server 2012, I can't see anything from MS saying this is or isn't a supported scenario?
We have already introduced a 2012 DC into the domain, it's a GC but hold no FSMO roles.
The system requirements for Directory Services (http://technet.microsoft.com/en-us/library/gg412831(v=ocs.14).aspx) states the highest supported OS for DCs as 2008 R2.
