Hyper-V: Converting a VHD to a VHDX

Windows Server Hyper-V introduces a new file format: VHDX

On Windows Server 2012 there’s a new virtual hard disk format with the extension “VHDX”.

As the Virtual PC Guy states in his blog:

There are a number of advantages to this format:

  • Support for greater than 2TB disks
  • Better performance for dynamic and differencing disks
  • Better handling of different disk sector sizes
  • And more…

How to convert?

Will the size of my files change?

Yes, the new .VHDX files will probably be slightly larger.

Here’s an example of a sample conversion:
