We have purchased a Windows Server 2025 license through CSP. However, we currently have an existing Windows Server 2016 server that needs to be activated.

Could you please advise whether it is possible to downgrade the Windows Server 2025 license to obtain a Windows Server 2016 product key for activation? If so, could you also let us know the correct process to request or retrieve the downgraded license key under CSP?

Thank you for your assistance.

    Yes, a Windows Server 2025 license can be downgraded to activate Windows Server 2016. According to the licensing policies, perpetual product licensing rights allow for downgrading to previous versions, typically following an n-1 or n-2 policy for most products. This means you should be able to obtain a product key for Windows Server 2016 from your Windows Server 2025 license.

    To request or retrieve the downgraded license key under the Cloud Solution Provider (CSP) program, you would typically need to follow these steps:

    1. Access the Partner Center: Log into your Partner Center account.
    2. Locate the Product Key: Navigate to the product details panel for your Windows Server 2025 license.
    3. Request the Downgraded Key: If the key is not readily available, you may need to contact Microsoft support or submit a support ticket to request the downgraded key specifically for Windows Server 2016.

    Ensure you have all necessary information ready, such as your product details and any relevant business justification for the request.
