Applies To: Windows Server 2012 Essentials, Windows Server 2012 R2 Essentials

Windows Server 2012 R2 Essentials supports up to 25 users and 50 devices. When your business needs exceed the limit, you can perform an in-place license transition from Windows Server 2012 R2 Essentials to Windows Server 2012 R2 Standard to remain license compliant.

After you transition to Windows Server 2012 R2 Standard, the user account and devices limits are removed, but the features that are unique to Windows Server 2012 R2 Essentials (such as the Dashboard, Remote Web Access, and client computer backup) still remain available. However, technical limitations for these features support a maximum of 100 user accounts and 200 devices. The client computer backup functionality will support backup of up to 75 devices.

Important

Windows Server 2012 R2 Standard requires a client access license (CAL) for each user or device in your environment. This is different from Windows Server 2012 R2 Essentials, which does not use the CAL model and does not come with any CALs. When transitioning from Windows Server 2012 R2 Essentials to Windows Server 2012 R2 Standard, you will need to purchase the appropriate number and type of CALs for your environment (most customers purchase user CALs).

Before the transition

  • Before transitioning from Windows Server 2012 R2 Essentials to Windows Server 2012 R2 Standard, you should fully back up the server data.

Important

Without a full backup of the server, you cannot restore the server to the state that it was in prior to the transition.

  • In addition, make sure that you read and understand the End User License Agreement (EULA) for Windows Server 2012 R2 Standard. To view the EULA:

    1. Open a command window as Administrator.

    2. Run the following command:

      dism /online /set-edition:ServerStandard /geteula: eula path (where eula path represents the location to which you want to save the EULA file; for example: C:\ws8std_eula.rtf). Be sure to use .rtf as the file name extension.

    3. Open the location where you saved the file, and then double-click the file to open it.

Transition to Windows Server 2012 R2 Standard

After you have decided to transition from Windows Server 2012 R2 Essentials to Windows Server 2012 R2 Standard, complete these two steps:

  1. Purchase a license for Windows Server 2012 R2 Standard and the appropriate number of user and/or device client access licenses for your environment.

    You can purchase a license for Windows Server 2012 R2 Standard from a Retail Outlet, a Distributor, or with the help of a Microsoft Partner.

Note

If you purchased Windows Server 2012 R2 Standard initially and exercised your downgrade rights to install one of your two virtual instances as Windows Server 2012 R2 Essentials, you do not need to purchase anything additional. If you purchase Windows Server 2012 R2 Standard through the Volume Licensing channel, you can download an ISO image and a product key for Windows Server 2012 R2 Standard from the Volume Licensing Service Center (VLSC). If you purchase Windows Server 2012 R2 Standard from any other channel, you can download an ISO image and an evaluation product key for Windows Server 2012 R2 Essentials from the TechNet Evaluation Center. Performing the transition as described in the next step will convert the evaluation product to a fully licensed and supported product.

  1. Open Windows PowerShell as Administrator, and then run the following command:

    dism /online /set-edition:ServerStandard /accepteula /productkey: Product Key (where Product Key is the product key for your copy of Windows Server 2012 R2 Standard).

    The server restarts to finish the transition process.

After the transition, the Windows Server 2012 R2 Essentials features remain on the server and are supported for up to 100 users and 200 devices.
