Regarding your last part I'm certain that you can't transfer the license from the hardware dongle to the software dongle. That's what I have read on several developers site. That you can have the license on a hard drive but if you transfer to the dongle then you can't go back.
Regarding the first part: Are you sure about that? I don't think you can de-authorize the hard drive if you don't do it from the hard drive itself. In theory you could then deactivate the licenses on a hard drive and put them on another but still be able to use it on the first one - if not connected to the Internet and not updating the License Manager.
If this procedure was possible there wouldn't be a problem. Of course you can do it if the hard drive is working but if you have a crashed hard drive you can't do it from another hard drive. And I don't even think that reinstalling everything etc. and the I-lok manager on the original hard drive (if the failure wasn't hardware related) would work because it's probably a combination of a written file & the hard drive unique serial/hardware number / whatever they use.
