You Need to Know : How to Converting existing Windows Server 2012 versions

  • [アーティクル]

  Hi all :

  At any time after installing Windows Server 2012, you can run Setup to repair the installation (sometimes called “repair in place”) or, in certain cases, you can convert to a different edition.

  You can run Setup to perform a “repair in place” on any edition of Windows Server 2012; the result will be the same edition you started with.

  For Windows Server 2012 Standard, you can the system to Windows Server 2012 Datacenter as follows:

  From an elevated command prompt, determine the current edition name with the command DISM /online /Get-CurrentEdition.

 

  Make note of the edition ID, an abbreviated form of the edition name. Then run DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula, providing the edition ID and a retail product key.

 

  And press Enter :

 

  Note : About KMS Client setup key , you can find it from : https://technet.microsoft.com/en-us/library/jj612867.aspx

  Press Y and the server will restart twice. When you logon again , the version is converted to Datacenter :

 

 

 

   Enjoy!

    Hi Raghu: You can use Dism /online /get-targeteditions command in Powershell to check your target OS version. You can not downgrade Windows Server 2012 Standard Edition to Windows Server 2012 Essentials.

    Hi Justin, I am trying to license my ServerStandardEval.  I have tried your method and is says that "this Windows image cannot upfrade to the ediion of Winsows that was specified. The uprgrade cannot proceed. Run the /Get-TargetEditions" When I run the Get-TargetEditions it tells me I can upgrade to standard or datacenter. Conflictin information??  Any thoughts?

    Never mind. I realized what I did wrong. I needed to put what my target licensed edition is and not what I currently had. Replaced ServerStandardEval with ServerStandard and it licensed right up.

    Hope this helps someone else!

    Hello,
    If that server already added role and promote it to a domain, what is the problem if we convert the Evaluate to Full retail?
    Thanks

    How to upgrade the Preview Version into Proper Retail OS of DC Edition. Unable to do so, following is the result:

    DISM /Online /Get-TargetEditions

    OS edition is Windows Server 2012 Datacenter

    The Output result is:

    -------------------------------------------------------------------------------

    The current edition cannot be upgraded to any target editions

    -------------------------------------------------------------------------------

    Thats it! This helped me a lot! It worked.
    Even in the MS TechNet-Site they have a wrong syntax (...product-key: instead of ...productkey)

    Hi Aca:
    No, you can't.
    You can not downgrade Windows Server 2012 Standard Edition to Windows Server 2012 Essentials.

    Hi Danish:
    Preview edition isn't complete edition, so you can't use this command.

    Hi Robert:
    Essentially, Hyper-V server is a server core edition of the Windows Server OS, and thus all the rules that apply for Windows Server Core installations (such as not being able to be upgraded from server core to full server) applies all the same to Hyper-V server.
