I have a new 2012R2 Server that I have installed AD DS on which is also hosting the forest. I have an another Windows 2012R2 server that I am attaching to that existing forest and getting the following error message:The functional level of the forest is incompatible with this operating system
The domain and forest functional level of primary domain is Windows 2012R2 still getting the error.
Please help on this issue
Thank you
