Upgrade Server Version RRS feed

  • Question

  • I am looking to upgrade some of my VM servers that are currently running 2008r2 and 2008 std and I want to go to server 2016, but have been told that I have to first upgrade to server 2012 and then to 2016. Can I buy 1 licnese for 2012 and run on them all since they are moving to 2016 or do I need to buy servers=# of license for 2012 and do I need any CAL's for 2012 since it is moving on to 2016. I appreciate any assistance you can provide

  • An in-place upgrade is risky and never recommended, better to clean install, patch fully and migrate roles or applications over, otherwise what you suggested should work fine.

  • Hi,

    In general, there are 2 ways for system upgrading:
    1. In-place upgrade
    2. Migration

    As it mentioned, it does not support in-place upgrade from Windows Server 2008 R2 to Windows Server 2016. It should be at least Windows Server 2012. 

    Please note that, there are limitations for in-place upgrade, such as OS version, language and etc. Please reference section “Upgrading previous retail versions of Windows Server to Windows Server 2016” in below link for the details:

    https://docs.microsoft.com/en-us/windows-server/get-started/supported-upgrade-paths

    Also, please confirm that installed server roles are supported to be upgraded - Server role upgrade and migration matrix for Windows Server 2016:

    https://docs.microsoft.com/en-us/windows-server/get-started/server-role-upgradeability-table

    If all pre-requirements are met, you can consider of in-place upgrading:
    Windows Server 2008 R2 -> Windows Server 2012/2012 R2 -> Windows Server 2016

    I would also recommend you to consider of migration, which will also keep your current configuration and data.

    Best regards,

  • For your questiona bout the CAL, you should order 2016's CAL and OS's license, as it's your final step. With the advice given by others, I suggest too a direct install on 2016 and migrate the role after if you can

  • Do a migration I have never had any luck with in place upgrades. Do you DC's first then migrate all your services one at a time. Once you have all the servers and services migrated upgrade your domain functional level.
