Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The process of moving to Windows Server R2 might vary greatly depending on which operating system you are starting with and the pathway you take.

Consult the specific TechNet Library topics for each server role you intend to install for details of additional steps that might be required.

In this case, install an additional domain controller on a server that runs a retail version and remove AD DS from the domain controller that runs on the evaluation version. Make note of the edition ID, an abbreviated form of the edition name. The server will restart twice. For the evaluation version of Windows Server Standard, you can also convert to the retail version of Windows Server Datacenter in one step using this same command and the appropriate product key.
