In Place Upgrade Of Windows Server Standard To Enterprise Or Datacenter Edition

If you need to upgrade a server running Windows Server 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 multiple Windows Server versions.

Typing DISM /Online /Set-Edition:ServerDataCenter /ProductKey:xxxxxx will upgrade the operating system.  All that’s required to complete the upgrade is a reboot.
