Windows Server 2016 downgrade to 2008 RRS feed

  • Question

  • Hello

    we are about to buy Windows Server 2016 + 30 USER CAL + 30 RDS CAL.

    We will not use Windows Server 2016 for obvious reasons, instead will downgrade to Windows Server 2008 R2.

    Can we use Windows Server 2016 USER CAL and RDS USER CAL on Windows Server 2008 R2?

    If not, how do you suggest we should proceed? I can't buy 2008 anywhere these days.

    Actually, there is no obvious reason.  It makes a lot of sense to deploy Windows Server 2016 if you are just getting started.

    Can we use Windows Server 2016 USER CAL and RDS USER CAL on Windows Server 2008 R2?

    Yes, on Windows Server CAL. No, on RDS CAL. Windows Server CALs are simply pieces of paper that say you have the client access licenses necessary to access the services of one or more Windows Servers. They are not installed anywhere. You must have CALs on at least the latest version.

    RDS CALs get installed into a licensing server, and the CAL version must match the version of the RDS server being accessed.

    Of course, you need to remember that licenses are legal agreements between you and Microsoft.  This is a technical forum, and the answer just provided is from an 'anonymous' technical person - not a lawyer.  You would be best served in getting answers to licensing questions by talking with a trained Microsoft licensing specialist.  Simply pick up the phone and call Microsoft.  They are happy to assist with clarifying licensing questions.

  • Thanks Tim

    I only posted here because our country does not have Microsoft support and after getting my call forwarded 5+ times and then dropped I quit trying and came here.

    I guess will go with Windows Server 2016,2016 CALs and 2008 RDS licences from other sources since there is no plan for our customer to move their software solution to another platform for another 3-4 years.

  • Hi,

    Yes, you can use Windows Server 2016 license + Windows Server 2016 CALs + Windows Server 2016 RDS CALs for Windows Server 2008 R2, assuming you are purchasing via volume licensing agreement.  Please reference the applicable Product Terms document and program agreement.  You should read the documents fully.  Below are some of the key portions in Product Terms document that relate to your question:

    • Universal License Terms ---> 3. Rights to Use Other Versions and Lower Editions
    • Windows Server product-specific entry --> 2. Product Conditions --> Down Editions
    • Glossary --> Down Editions

    Once purchased you should be able to access necessary .iso file and product key for 2008 R2 via VLSC.

    In regards to the RDS CALs, you will need to install RD Licensing Role Service, Activate the server using RD Licensing Manager (licmgr.exe), and then install the RDS CALs using the Install Licenses wizard.  They will install as 2008 RDS CALs.  If you have an issue installing the RDS CALs you may switch to Web or Telephone connection method in Properties and then use https://activate.microsoft.com or call the Clearinghouse.

    In RD Session Host Configuration (tsconfig.msc) you need to set the licensing mode to Per User and Specify the name of the RD Licensing server.

    Thanks.

    -TP
