I've just done my first migration to our new Hyper-V setup using Disk2Vhd. Used it to move our Print Server VM on XenServer to our new 2012R2 Hyper-V SAN and all seems well!

Giddy with all the excitment, I just also transferred an existing physical machine to it as well - this was hardware that I was hoping to retire but ended up installing the BTEC testing software on. We had a hard drive failure light come on the other day and seeing it has no warranty cover I was a little concerned (although reseating the drive seems to have got rid of the red light!).

Chuffed. Me likey!
