Windows Server 2008 R2 includes a command-line tool called the Deployment Image Servicing and Management tool, or DISM. It's functionally equivalent to the Windows Anytime Upgrade feature in client versions of Windows. You can run it from an elevated command prompt.

If you need to upgrade a server running Windows Server 2008 R2 Standard to either the Enterprise, or Datacenter editions, it’s possible to do so online, without re-installing Windows. Open an elevated command prompt and type DISM /Online /Get-CurrentEdition.  This will return the current Windows version. Type DISM /Online /Get-TargetEditions to list the Windows editions to which this server can be upgraded. If you type DISM /Online /Set-Edition:ServerDataCenter you’ll get the message in the screenshot below.  This is because even if you’re using a KMS server for internal activation, you have to provide a product key.  Fortunately, Microsoft have a page that lists the KMS client setup keys  http://technet.microsoft.com/en-us/library/ff793421.aspx .  On this page you can find keys for Windows Server 2008 R2 Enterprise and Datacenter. Typing DISM /Online /Set-Edition:ServerDataCenter /ProductKey:xxxxxx will upgrade the operating system.  All that’s required to complete the

Windows Server 2008 R2 introduces a new command-line utility, DISM, the Deployment Image Servicing and Management tool.    One of DISM’s many useful features is the ability to use its edition-servicing commands to upgrade an R2 installation without requiring install media.  This is functionally equivalent to Windows Anytime Upgrade in a Windows 7 client install, and can be performed on both an online or offline image, and on both full Server and Server Core installations. Upgrades using the edition servicing method are quick, and don’t require a full reinstall of the operating system.  Deployed roles and features, and other characteristics (machine name, user and admin accounts, etc) are persisted forward.     Because the target editions are staged within the image, only the updates necessary to move from edition to the next are applied. The upgrade options are limited to edition families, and are irreversible – you can’t downgrade once you’ve gone up an edition.  Additionall
