I have an Exchange Server currently hosted on a VMWare vSphere box. I want to migrate it to a Hyper-V box. I installed V2V Easy Converter on the Hyper-V box and ran the conversion...It moved over the data drive which is around 400 GB and then the OS drive at around 100 GB. This took from 8:45 pm until 6:00 am the next morning. Just as I thought it was going to complete it wiped out the 400 GB data drive and began moving it over again! What happened?
