Can't upgrade Windows VM because of Microsoft Hyper-V SCSI Controller

Can't upgrade Windows VM because of Microsoft Hyper-V SCSI Controller - Resolution with screenshots

Q: I am trying to upgrade a VM running Windows 2003 R2 with SP2 to Windows 2008. I get this message and can't continue:

You must make the following changes before upgrading Windows. Close Windows installation and contact the device manufacturer to get update drivers for the following devices: SCSI and RAID controllers: Microsoft Hyper-V SCSI Controller.

A: You need to remove SCSI Controller in Hyper-V VM settings. Quoted from Microsoft has an article
To resolve this problem, remove the SCSI Controller from the Windows 2000 SP4-based virtual machine. To do this, follow these steps: 1.Start Hyper-V Manager.
2.Under Virtual Machines, right-click the Windows 2000 SP4-based virtual machine, and then click Settings.
3.Under Hardware, click SCSI Controller, click Remove Controller, and then click OK.
4.Right-click the Windows 2000 SP4-based virtual machine, and then click Start.
Installation of Integration Components from Windows Server 2008 SP2 instead of SP1 will prevent the Windows Server 2000 guest from encountering a bugcheck on boot. This is accomplished by loading a null driver. When you view SCSI and RAID controllers in Windows 2000 Device Manager, the miniport driver will be listed as "Storage miniport driver (not supported)."
