VMDK to VHDX

Follow steps:

If you counter following error:

ConvertTo-MvmcVirtualHardDisk : The entry 1 is not a supported disk database entry for the descriptor.

In my case it was entry 4

Follow these steps:

  1. download and extract dsfok tools
  2. use dsfo.exe "c:\temp\disk2.vmdk" 512 1024 descriptor1.txt to extract the descriptor
  3. edit the descriptor file in Notepad++: comment the above mentioned line (as I added the extra single character (#) I also deleted one NULL character from the end to keep the file size of 1024 bytes (not sure if this is needed).
  4. use dsfi.exe "c:\temp\disk2.vmdk" 512 1024 descriptor1.txt to inject the descriptor back into the VMDK
  5. repeat these steps for the other disk (my VM has two .vmdk files)
  6. reissue the ConvertTo-MvmcVirtualHardDisk command

The converter is no longer officially supported by Microsoft and the link available everywhere (download/details.aspx?id=42497) doesn't work anymore.
Fortunately, there's a Chocolatey package that contains a direct link to the installer. I mirrored it here.

@xavery - thanks, you saved me today by hosting that package. I could not find it anywhere on the internet. All the links are 404

@xavery - Thanks, I have updated the Gist.

Between steps 1 and 2 should be a step 'Run the downloaded installer'.

As of July 6, 2021, even with the MS Virtual Machine Converter, I could not convert my vmdx files to vhdx. I am using VMware Workstation 16 Pro (16.1.2 build-17966106).

Use qemu and its easy single command-line for conversion.

Show, interesting.... did not know this method.
In reality it is similar to MVMC, with a single command after extracting the .ova

ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath "" -VhdType DynamicHardDisk -VhdFormat vhdx -destination ""

With "qemu" does not generate the error "is not a supported disk database entry for the descriptor." ?

No it worked smoothly.. no errors pretty straight forward command.

This also works but due to some reason not working on Win11 after recent updates.
You can try on Win10, maybe it works there still.

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" clonehd --format vhd "disk001.vmdk" disk-OS-v2.vhd

Cool... I'll test it.... thanks sukesh-ak !

Hi, Does qemu delete all the VMware environment dependencies tools also while converting .vmdk to .vhd? or it cloned exactly the same file in a different format?

Just converted the disk file format to new format. That's all.

I was looking forward for a straight solution, that did the trick! Thank you!

For me it worked like this:

STEP 1 - Download and Install: http://download.microsoft.com/download/9/1/E/91E9F42C-3F1F-4AD9-92B7-8DD65DA3B0C2/mvmc_setup.msi

STEP 2 - Run power shell as administrator.

STEP 3 - PS> Import-Module 'C:\Program Files\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1'

STEP 4 - PS> ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath "D:\Virtual Machines\Windows 10 x64\Windows 10 x64.vmdk" -VhdType DynamicHardDisk -VhdFormat vhdx -destination "D:\Virtual Machines\Windows 10 x64\Windows 10 x64.vhdx"

Don't forget to check the syntax of commands and punctuation etc... And enjoy

This all looks very promising, did anyone ever write a script that automates this process? I‘d like to install Whonix in Hyper-V but didn’t get it to work so far
