Convert vmdk to vhdx

Hi,

I have a client that needs his vmdk files converted to vhdx. I tried to use the MVMC 3.1 tool but it just doesnt get thet job done.

So I tried to run a powershell command to do this. Here is the syntax I have used.

import-module 'C:\Program Files\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1'
ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath "C:\WindowsServer2008STD.vmdk" -DestinationLiteralPath "M:\WinServer2008Std\" -VhdType DynamicHardDisk -VhdFormat Vhdx

I have not yet tried the converted vhdx files, but the original file size of one of the vmdk is 80Gb and after this conversion the file size is only 59Gb. Another vmdk file is 250Gb and after the conversion the vhdx is only 48Gb.

Has anyone done this yet? This can't be normal.
