Thanks for your ultra fast response.
The problem is that the ESXi server is in a completely different office location than the ESX & I don't want to move a heavy server out of the data centre & drive it from Location A to Location B.
Does anyone else or yourself have had any experience with going into "datastore1" on ESXi & selecting "Browse Datastore" & copying the VM folder to a USB device or laptop then restoring it to ESX Sever.
(I know that doing this will change a Thin Provision to a Thick Provision)
If there is another way that is guaranteed to work I would also like to know?
