Hyper-V Program Manager
Yesterday I showed you how to convert a VHD file to a VHDX using the Hyper-V Manager user interface. Today I want to show you that it is even easier to do using PowerShell:
All you need to do is run the following command:
Convert-VHD .\test.vhd .\test.vhdx
We will figure out whether you want the new file to be a VHD or VHDX depending on the file extension that you provide. You can also specify whether you want a dynamic or fixed disk – but that is optional.
Excellent , just like VHDtool.exe but running from powershell.
Hi ben, is the 'FileSize' before & after conversion correct?
Funny thing is I did this just yesterday on converting some large fixed disk .vhd to .vhdx A significant benefit is you can open up additional powershell instances and convert more than one .vhd at a time. Worth pointing out as well that the new file will take on the characteristics of the old (as far as I understand) that is to say the target .vhdx will be a dynamic .vhd if the source was dynamic, and likewise for a fixed disk .vhd being converted. Otherwise as you point out you can override the default behaviour.
As an aside, I'd love a way of being able to easily convert a .vhd or .vhdx file to a wim. Either by a one line tool or by a script.
Yes, VHDX files tend to be a bit larger than VHD files - as we preallocate a buffer for performance reasons.
Hi Ben, what is the use of -passthru option in the convert-vhd command
