Hyper V .VHD files unable to be transferred

Hyper V .VHD files unable to be transferred anywhere,

Moving Hyper V servers to a new server,

I have been able to move all VHD files except for 1 particular server,
i have stopped all related services to hyper V while transferring

I have tried a number of ways to transfer the VHD file across but a disk error keeps appearing or it just fails,
These include
- Windows file transfer
- Vise Versa Application to copy files
- VMW Converter VtoV
- Windows Backup

I have tried to copy to Local Disks, External Hard Drives, to the new server or NAS with no success

The VHD Files are running the virtual server fine
I have determined that issue is some corrupt sectors
- I am afraid if i run chkdisk that it will corrupt the files or host server

does anyone have any ideas?

Thanks in advanced

    Hi Paul,

    Did you tried a straight Export and import?

    I assume that you have Windows server 2008 R2 as the Hyper-V Host. If so, Stop the VM
    Export the VM
    Copy the exported folder to the new server
    Import VM
    Locate the export folder

    Yes i have tried the export function, unfortunately this stalls
    It is a 140GB file and it roughly stalls or errors on all transfers at 48-62GB

    This seems like the export/copy is failing while reading the corrupted area in the disk. If thats the case, its difficult to get the VM exported. As you still have the VM up and running, I would prefer to take an application level backup and configure it on a new VM.

    Accepted Solution

    Ok this was my solutions to the issue:
    Even though previously this had failed i decided to give it another go,

    Using VMW Converter,
    I ran a conversion from the Host OS to convert the Virtual machine as a Physical Powered On Machine
    Once the VMDK were completed
    I ran a conversion tool to convert the VMDK to VHD
    Transferred the VHD files to the new HyperV server
    Created new hyperV machine attaching the Server VHDs that were transferred
    Powered On
    Job Complete
