Question : Hyper-V machines missing after Windows upgrade

Hi,
I recently did an in place upgrade of Windows Server 2008 Standard to Windows Server 2008 Enterprise.  Unfortunately, now I'm finding that my VMs are no longer in Hyper-V manager.

I came across this article too late:

Luckily I did export my machines, but that was 2 days ago.  I'd really rather not lose 2 days of work.

Should I just create new virtual machines and use the .VHD file?  I know that this can cause problems.

Please advise (quickly if possible .. this is a slight emergency)

Answer : Hyper-V machines missing after Windows upgrade

First of all. Copy one VM virtual disk files (so we keep the originals just in case). Move that to a different folder, and yes, create a new VM, and set it to use those files. It will most probably work, and it's worth the try. You don`t loose anything but time. If not, you will need to go the hard way...
