How to upgrade Microsoft Windows 10 Enterprise to Microsoft Windows 11 Enterprise with downgrade rights to use at least two prior versions? Which license should I purchase?

Dear Alice,

To address your questions:

a) Upgrade Path to Windows 11 Enterprise Since you're currently using Windows 10 Enterprise LTSC 2021 under a CSP Upgrade license (DG7GMGF0D19L), upgrading to Windows 11 Enterprise requires a valid license that supports both the upgrade and downgrade rights.

b) Recommended License Option The license you referenced — Windows Enterprise Device ALng Upgrade SA OLV D 3Y Aq Y1 Ent (KV3-00355) — is indeed a suitable choice. It includes:

Upgrade rights to Windows 11 Enterprise

Software Assurance (SA) benefits for three years

Downgrade rights to at least two prior versions of Windows Enterprise, which meets your requirement

Eligibility under the Open Value Licensing (OVL) program

This license ensures flexibility for your deployment strategy, whether you're moving forward with Windows 11 or maintaining compatibility with earlier versions.

c) Additional Considerations Please ensure that your devices meet the hardware requirements for Windows 11 Enterprise. You can find detailed specifications on the Windows 11 documentation.
