I have two ESXi 5.1 machines, Each machine has two hard disks. I believe one drive on each machine is going bad and I have new, larger replacements for them. One is the boot drive with a datastore and the other is an additional drive with a datastore.
Is there a disk copy utility that will simply copy the old drive to the new? Moving suff around (and reinstalling on the boot drive) could take a while.
