Actually its was an old server and there was some problem with the RAID level i cannot bring the server up ,but since the VM volume was available i was able to copy paste the whole VM folder.

make a copy of the same and create new vm and connect the VHD and check weather it works or not... actually if it's having restore points then it's difficult to copy and run the VM by coying folder...

connect the VHD : it's not convert

connect means when you create new vm on the hyper-v host the process will as you to create a vhd or attach existing vhd so use the existing option and point to this vhd path

VHD is generation 1

VHDx is generation 2

if you are working on windows 2012 or later

On the newly installed host create a new Gen1 VM.
Attach the VHD file(s) to the VM in the order they were in on the original host.
Boot.
You may need an ISO of the guest OS to run Repair to restructure the boot configuration database.
Once in the networking will need to be set up once again.

If the VM is not a DC then workgroup it and re-join the domain. All will be okay.

The other solution for this is to importing the VHD on Hyper 2012 R2 instead of 2008
