Windows server 2019 Upgrade virtual machine version in Hyper-V #hyperv #winserv #hybrid

Why should I upgrade the virtual machine configuration version?

When you move or import a virtual machine to a computer that runs Hyper-V on Windows Server 2019, Windows Server 2016, or Windows 10, the virtual machine"s configuration isn’t automatically updated. This means that you can move the virtual machine back to a Hyper-V host that runs a previous version of Windows or Windows Server. But, this also means that you can’t use some of the new virtual machine features until you manually update the configuration version. You can’t downgrade the virtual machine configuration version after you’ve upgraded it.

The virtual machine configuration version represents the compatibility of the virtual machine’s configuration, saved state, and snapshot files with the version of Hyper-V. When you update the configuration version, you change the file structure that is used to store the virtual machines configuration and the checkpoint files. You also update the configuration version to the latest version supported by that Hyper-V host. Upgraded virtual machines use a new configuration file format, which is designed to increase the efficiency of reading and writing virtual machine configuration data. The upgrade also reduces the potential for data corruption in the event of a storage failure.

 

With PowerShell we check what versions I have running

Get-VM * | Format-Table Name, Version

As you can see I have version 5.0 – 9.0 running time for some upgrading.

This VM has version 5 and I’m upgrading this to version 9.0 , Windows server 2019 default.

Microsoft Windows 10 October 2018 Update/Server 2019 9.0     True

Update-VMVersion HYD-DC1 

Confirming and done.

If you want to upgrade all vm’s   then use a *

Update-VMVersion *

Get-VMHostSupportedVersion –Default

 

Microsoft Windows 10 October 2018 Update/Server 2019 9.0     True
