Update Windows 10 VM to Windows 11

[Afox]

Hello,

did anyone successfully update a Windows 10 VM to Windows 11? Is it possible if you just set the OS type to Windows 11/Server 2022 and add a TPM device? Any other actions required?

Thanks and best regards

Just a heads up for anyone who thinks about it:

You first need to download the PC Health Check App
and then Windows 11 Installation Assistant

For being able to install Windows 11 following requirements need to be fulfilled:

• Your CPU needs to be in the supported CPU list which means you need to set the CPU type to host for your guest
• Minimum two CPU cores
• Your system disk needs to be larger than 64GB
• Your guest must have more than 4GB RAM
• You need to add a TPM 2.0 state to your guest
• Your guest must support Secure Boot meaning you need to set OVMF (UEFI) as BIOS setting and add an EFI Disk with pre-enrolled keys

I did it recently!

If you don't already have one, you need to also create an EFI disk. After I added the TPM and EFI disk, I ran health check to confirm it was recognized and then went through the Windows 11 upgrade process. I cloned my VM before the upgrade just in case. Be prepared to start over and rely on your clone/backup if you need to. I didn't document it, but I had some issues with getting it to boot in OVMF after the switch from SEABIOS.

I had some complications - this all started p2v (migrated a physical workstation to proxmox) and the workstation has migrated from Vista -> 7 -> 10 before it got to Proxmox, with all of the built up problems you can imagine. I got it working initially using the old SSD in SATA pass-through mode before using clonezilla to copy the disk over to my lvm. The first time I got it upgraded to 11 and re-launched, none of my old software would load (which was the only reason I kept this install around), so I wiped it and started over from my clone, which worked the second time around.

I still haven't been able to convert the disk over to SCSI from IDE which is a bummer performance wise but works fine for my purposes.
