- > If you move this virtual machine to a Hyper-V host that runs Windows Server 2012 R2, use the **-Version** parameter with **[New-VM](/powershell/module/hyper-v/new-vm)** to set the virtual machine configuration version to 5. The default virtual machine configuration version for Windows Server 2016 isn't supported by Windows Server 2012 R2 or earlier versions. You can't change the virtual machine configuration version after the virtual machine is created. For more information, see [Supported virtual machine configuration versions](../deploy/Upgrade-virtual-machine-version-in-Hyper-V-on-Windows-or-Windows-Server.md#supported-virtual-machine-configuration-versions).
