I have some Hyper-V VMs which are dynamic disks. I want to convert them to basic for the sake of online VSS backups. I know that this conversion in Windows (if the option was not greyed out in the VMs for me...) requires a format of the HD/loss of all data. Products like http://www.dynamic-disk.com/dynamic-disk-convert-server.html claim to do this with no data loss. Is this really possible? Is there a way to do what I want with no data loss?
