I need some justified opinion on the following matter.
I currently have a Domain Installed on a Windows 2008 64bit (Not R2), running on an HP DL380 G6 Server, and i have MS Exchange 2010 running on the same server. (I know that this is not recomanded by microsoft to have the same server as a DC and Exhcange, but this is how it happened due to some budjet issues.
Now i want to get a new server (HP DL 380 G7) and i will install on it Windows 2008 R2.
My question is which role should i move to the new server and if the answer is Exchange 2010, How can that be done?
Note also that my current DC is also a File server.
