Able to convert 2016 server core (Standard with Non-GUI) to Hyper-V Server core? RRS feed

  • Question

  • Hi Microsoft

    I'm hoping someone can help me find a path of least resistance.

    We have a VM-Host server that was built with the incorrect operating system. The evaluation version of Server 2016 Standard without the Desktop Experience (core) was installed and then licensed VMs loaded on.

    The server is now turning itself off because of a licensing issue (the evaluation has expired).

    We have gotten around this by rearming the evaluation, but this only buys us more time until we have to fix the issue.

    We need to convert the license from the Standard version to Hyper-V Server (both server 2016) but unsure on how to do this on a core version of the server or if this is even possible.

    Alternatively we could export the VMs and rebuild the VM Host from scratch but this would prove more difficult and we would need to hope the VMs came back to life on the new machine, moving them between versions.

    Can anyone help?

  • Unfortunately there is no option to convert from Windows Server 2016 to Hyper-V Server 2016, you will need to reinstall your host.

  • Hi,

    Thanks for posting in our forum!

    Did you want to convert Windows Server 2016 core to Hyper-V Server core?

    It's crazy. As far as I know, we can't do it. We can only convert the Windows Server core to Windows Server GUI.

    So now, you should export your VM and recreate the Hyper-V host, then import the VM to the new Hyper-V host.

    Hope this can help you, if you have any question, please feel free to let me know.

    Best Regards,

    Daniel

    That was a feature of Windows Server 2012/R2. You cannot convert Windows Server 2016 from CORE to GUI or vice versa.
