Import VHD to Windows Hyper-V 2016

Hello,

We're unable to import a VM with a VHD to Hyper-V 2016 - it comes up with a page that states "No virtual machine files found".  I've combed the documentation, but I don't see anything about dropping support for the VHD file format.  Is VHD import still supported in Hyper-VM 2016?

Thanks,
Jason
