I don't think we understand what you want. Tell us what you are wanting to
accomplish, what your goal is. Maybe then we can help you. From what I've seen
thus far, it doesn't sound like copying entire partitions from one machine to
another is what you should really be doing. All that will do is exactly clone
the disk of the server onto the client. That will break many things, not first
of which you'll have two computers on the same subnet with the same IP address
and hostname.
