Ugrading Windows Server 2008 R2 from Standard to Enterprise

Ugrading Windows Server 2008 R2 from Standard to Enterprise

Log onto the server you want to upgrade

To get DISM
#1 - Right ckick on Windows PowerShell, select Run as Administrator

To Find Out Current Server Edition
#2 - Type in: DISM /online /Get-CurrentEdition
Output:
Current Edition : ServerStandard
To Find Out Possible Editions to Upgrade To
#3 - Type in: DISM /online /Get-TargetEditions
Output:
Target Edition : ServerDataCenter
Target Edition : ServerEnterprise


To Run the Actual Ugrade
#4 - Type in: DISM /online /Set-Edition:ServerEnterprise /productkey:ABCDE-ABCDE-ABCDE-ABCDE-ABCDE 

The process will change the product key, remove the Standard package, install the Enterprise package, then ask for a reboot. After reboot I would check for any updates.

A couple of issues:
* - The server can not be a DC
* - The product key will not be acceted if it a VLK that is the same for Standard and Enterprise edtions.

* - You must use a default KMS key to run the upgrade. The generic KMS client key for Windows 2008 R2 Enterprise is 489J6-VHDMP-X63PK-3K798-CPX3Y
