VM configuration version The VM upgrade process has changed in Windows Server 2016. In the past, when you imported VMs to a new version of Hyper-V, they were automatically upgraded. However, it was not always easy to identify which VMs were imported from a previous version of Hyper-V and which were newly created. That's because the VM configuration version upgrades automatically with the host upgrade. The real challenge, however, was that you couldn't roll back the VM to a previous configuration version. The VM version determines with which versions of Hyper-V the VM’s configuration, saved state, and snapshot files are compatible. In Windows Server 2016, the VM configuration version upgrade process is no longer automatic. This makes it possible for you to move the VM to a server running an earlier version of Hyper-V, such as Windows Server 2012 R2. In that case, you do not have access to new VM features until you manually update the VM configuration version. All VM capabilities remain compatible, such as live migration, storage live migration, and dynamic memory. Hence, upgrading a VM is now a manual operation that is separate from upgrading the physical host. It is important to note that when you upgrade the configuration version of the VM, you cannot downgrade it. If you use VMs that were created with Windows Server 2012 R2, you will not have access to new VM features until you manually update the VM configuration version. VMs with configuration version 5.0 are compatible with Windows Server 2012 R2 and can run on both Windows Server 2012 R2 and Windows Server 2016. VMs with configuration version 6.0 are compatible with Windows Server 2016 but will not run on Hyper-V running on Windows Server 2012 R2. The following table lists the supported versions of the configuration version on Windows: Hyper-V host Windows version Windows 10 Anniversary Update 8.0, 7.1, 7.0, 6.2, 5.0 Windows Server 2016 Technical Preview 7.1, 7.0, 6.2, 5.0 Windows 10 build 10565 or later 7.0, 6.2, 5.0 Windows 10 builds earlier than 10565 6.2, 5.0 Windows Server 2012 R2 5.0 Windows 8.1 5.0 Supported VM configuration versions Upgrading the configuration version To upgrade the configuration version, shut down the VM and, at an elevated Windows PowerShell command prompt, type the following command: Update-VmConfigurationVersion vmname or vmobject. To check the configuration version of the VMs running on Hyper-V, from an elevated command prompt, run the following command: Get-VM * | Format-Table Name, Version To illustrate the configuration version upgrade process, the following example determines the VM configuration version imported from a host running Windows Server 2012 R2 and then shows how to upgrade its configuration version. In this case, as expected, the configuration version of the VM is 5.0 as indicated in Hyper-V Manager (see Figure 2-14). Figure 2-14: VM version number 22 CHAPTER 2 | Software-defined datacenter
You can confirm this by using Windows PowerShell as follows: PS C:\Users\Administrator> Get-VM vm02 |Format-Table Name, Version Name Version ---- ------- vm02 5.0 As stated previously, you must shut down the VM and run the following Windows PowerShell command to upgrade the configuration version of the VM: PS C:\Users\Administrator> Update-VMConfigurationVersion vm02 Confirm Are you sure you want to perform this action? Performing a configuration version update of "vm02" will prevent it from being migrated to or imported on previous versions of Windows. This operation is not reversible. [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): Y PS C:\Users\Administrator> When checked again, the configuration version in Hyper-V Manager now has the value 6.0, as depicted in Figure 2-15. Figure 2-15: Upgraded version number Again, you can confirm this by using Windows PowerShell, as follows: PS C:\Users\Administrator> Get-VM vm02 |Format-Table Name, Version Name Version ---- ------- vm02 6.0 As an aside, if you get any startup failure after a VM configuration version upgrade, try turning on secure boot and then run the following Windows PowerShell command: Set-VMFirmware -VMName "VMName" –SecureBootTemplate MicrosoftWindows The VM configuration version is successfully upgraded, which means that the VM has access to new VM features introduced in Windows Server 2016. Upgrade process considerations You need to be aware of several considerations before you upgrade the configuration version of a VM: You must shut down the VM before you upgrade the VM configuration version. The configuration version upgrade process is one way; that is, when you upgrade the configuration version of the VM from version 5.0 to version 6.0, you cannot downgrade, and, hence, afterward you cannot move the VM to a server running Windows Server 2012 R2. The Update-VMConfigurationVersion cmdlet is blocked on a Hyper-V cluster when the cluster functional level is Windows Server 2012 R2. You can still move the VM between all of the nodes in the Hyper-V cluster, however, when the cluster has a mix of both Windows Server 2012 R2 and Windows Server 2016.
