Convert Shared VHDX to VHD Set with Windows Server 2016

Q. How can I convert Shared VHDX to VHD Sets?

A. There is no automatic upgrade from Shared VHDX to VHD Set when you upgrade to Windows Server 2016. Instead you need to manually convert them using a four-stage process:

1. Turn off the VMs that are connected to the Shared VHDX
2. Remove the Shared VHDX from the VMs using Remove-VMHardDiskDrive or using Hyper-V Manager
3. Convert the shared vhdx into VHD Set format using Convert-VHD
4. Add the VHD Set files back to the VM using Add-VMHardDiskDrive or using Hyper-V Manager
