Converting a physical server with Dynamic Disks to a Hyper-V VM

Of all the things that suck in IT, this is one of my least favorite.  Here’s the scenario.  A client has a Dell server running Server 2003 with dynamic mirrored disks.  The server is old and for some reason the network won’t communicate after a reboot.  I’ve completely reinstalled TCP/IP and the driver, yet nothing has worked.  It’s gone through several disk failures as well, so I figured it’s time to virtualize the bastard and see if that helps.  I’ve done several P2V conversions of servers before, so I figured this would be pretty easy.  Holy crap was I wrong.  Since I’m using Hyper-V in this scenario, I fired up disk2vhd and let it work.  After setting up the new VM and importing the disks, I quickly realized it wasn’t booting.  That’s when I discovered the source disks were dynamic.  I tried to convert them to basic with a hex editor, but everything I attached the vhdx’s to thought the partitions were not formatted.  This led me to do some research on other methods to convert the source disks, but I couldn’t find anything that claimed to do the job without reinstalling Windows.  Being the persistent bastard that I am, I decided to install VMware Converter and make a VMware VM out of it.  I didn’t have a way to run the VM, but that allowed me to use Starwind V2V Converter and convert each vmdk to vhdx.  I started with just the boot drive to verify my theory was correct.  It worked!  Not only is the disk now basic, it booted on the first try!  I converted the second disk, tested it, and then powered down the physical server for good.
