I am working on moving a bootable VHD running Debian to a new VM on Windows Server 2022. This VHD is currently functional.

If anyone can provide some things to check during this process, it would be appreciated.

    Moving a bootable VHD running Debian to a new VM on Windows Server 2022 involves a few steps to ensure a smooth transition. Here are some things to check and consider during this process:

    • Before making any changes, ensure you have a backup of the VHD to prevent data loss in case something goes wrong during the migration process.
    • Before moving the VHD, shut down the Debian VM gracefully to avoid any data corruption.
    • Copy the VHD file to the new VM host where you want to run it. You can use tools like Windows File Explorer or command-line tools like Robocopy to ensure a successful transfer.
    • Create a new VM on the Windows Server 2022 host where you want to run the Debian VHD. Use the copied VHD as the boot disk for this new VM.
    • Ensure that the new VM's settings (CPU, memory, network adapter, etc.) match the original Debian VM to avoid any compatibility issues.
    • Start the new VM and check if it boots up successfully. You may need to enter the BIOS/UEFI settings to ensure that the VM is set to boot from the VHD.
    • Check the network configuration on the new VM to ensure it matches the original Debian VM. This includes IP address, subnet mask, gateway, DNS settings, etc.

    By following these steps and considering these points, you can increase the chances of successfully moving a bootable VHD running Debian to a new VM on Windows Server 2022.

    Hi Dylan,

    Thanks for your post. When you migrate the Debian VHD to VM, please note the following notifications.

    1. Creating file systems on VHDs larger than 2 TB isn't supported.
    2. Starting with Debian 8.3, the manually installed Debian package "hyperv-daemons" contains the key-value pair, fcopy, and VSS daemons. On Debian 7.x and 8.0-8.2, the hyperv-daemons package must come from Debian backports.
    3. The latest upstream kernel capabilities are only available by using the kernels available in the Debian backports repository.
    4. While Debian 7.x is out of support and uses an older kernel, the kernel included in Debian backports for Debian 7.x has improved Hyper-V capabilities.

    Best Regards,
