VMware vCenter converter with Hyper-V import
One of the caveats the vSphere 4.0 was the vCenter Converter Client. The one bundled with vCenter 4.0. Did not do the P2V with as a destination having thin provisioned disks. In that time, you had actually two choices.
First: Do the conversion, and then storage vMotion to another datastore. (with the option to specify thin disks as a destination format). You say, not a big deal… but wait.. Not a big deal for guys with enterprise plus licensing option… Well, if you stop the VM you can also cold migrate with an option for the Thin provisioned disks too….
Second: To install an VMware Converter Standalone edition onto the physical box and do the conversion from within the physical server. That’s what I usually did, because I had the best conversion results too.
