Do you know what the license locks against. Does it use the MAC address
like sensible[1] licensing systems?

I'm not sure what the license has to do with which install method you
choose. Surely you will have to generate a new license whatever you do?
Or does this machine already have a license?

I'll admit to having a philosophical dislike of imaging. It can lead to
people forgetting how to set the machine up from scratch. But it is the
fastest way to get a working a system. When imaging we tend to do it the
old school way by using a rescue disk and writing a disk image with dd,
but if you are going to be doing it frequently it's probably better to
learn how to use mondo rescue.
