Hello,
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.

Please advise
Regards,

You have two option
1. Either make that a Dc and when the AD information has been replicated to the other DC, demote this existing DC.
2. Install Exchange 2010 on that server so that you would have 2 exchange server in the enviornment.During installation make sure that it is a member of the same organization.After you have done that mount the old database to the new server and then uninstall this existing server.

Commented:
You don't have option 1. Or at least option 1 is not supported by MS (cannot demote a DC running Exchange without potentially seriously breaking Exchange). Therefore if you want to separate the roles, you must move or reinstall Exchange.

Parallel installations of Exchange should not be a serious issue, it's well supported and well documented. Once the new Exchange server is up, and you have moved content, you can start looking at removing the old one.

Exchange / DCPromo thing, see the notes under "Directory Server Architecture" then "Installing Exchange 2010 on Directory Servers":

The actual process is very similar to the move from 2007 to 2010. It's always worth reviewing the documentation for these things, and checking system stability at every stage of your deployment:

Does that get you any further?
