Windows Server 2008 Downgrade Rights

General Downgrade Options and Rights

Included with a Windows Server 2008 license is the right to run an instance of any previous version of Windows Server (also referred to as a downgrade or downgrade instance) in place of an instance of Windows Server 2008. The Windows Server 2008 license terms apply to the use of the previous version. If the earlier version includes different components, any license terms for those components in the license terms that come with the earlier version apply to your use of them. At any time, a customer may replace an earlier version with the newer licensed version of the software. However, more information on obtaining earlier versions can be found below and more information on support for earlier versions of Windows Server may be found at http://support.microsoft.com/lifecycle.

Microsoft provides product downgrade rights to customers because in many channels, only the latest version of a product can be acquired. By providing customers with downgrade rights, customers are able to acquire the right to use the latest version of a product while still deploying an earlier version of that product. Downgrade rights allow Microsoft to support the following scenarios:

  • Those customers with existing licenses of previous versions of the software who are not yet ready to migrate their servers to the newest version but wish to license the new version in preparation for the transition.

  • Those customers with existing licenses who are running legacy applications requiring the earlier versions of the operating system software.

Using downgrade rights in these scenarios, customers are able to purchase additional capacity to support their legacy applications now, and then plan their platform migration for a time that is convenient for their business.

Windows Server 2008 Downgrade Licensing Rights

The following table shows the available downgrade options that each edition of Windows Server 2008 you are licensed to use. If you already have media and product activation keys for the earlier version of the product that you have downgrade rights to, you can use that media and keys to downgrade to an earlier version. If you do not have media and keys, please see below on how you can obtain a fulfillment kit only for Windows Server 2003 R2 Standard Edition and Windows Server 2003 R2 Enterprise Edition only.
