I didn’t know about that difference between 2012 R1 and 2012 R2 Hyper-V. I think what will really be a major factor is whether or not the virtual disk is thin or thick. If it’s thin, I believe it will take seconds.

Since this is not 2012r2 I need to shut down the guest to exapnd the disc, what I'm trying to guess-estimate is how long the guest will be down to expand the guest. Hardware is 2 x 4 core 1.86 XEON and 48GB of ram thanks
