Are you using the vFlash Read cache for your VM's?
You need to disable the cache and then migrate the VM. Or you will end up with an error.

To deallocate Flash Read Cache on a virtual machine configured to use this feature:

1. Open the vSphere Web Client.
2. Navigate to the Hosts and Clusters view.
3. Select the host on which the virtual machine is running.
4. Click the Related Objects tab.
5. Right-click the virtual machine and Click Edit Settings.
6. Select and expand the hard disk that is assigned the Flash Read Cache.
7. Set the amount of Flash Read Cache assigned to 0.
8. Click OK to apply the changes.

8589934592 bytes = 8GB not 64GB.
