Your best bet is to look into xentrace & xenalyze,
I'm currently thinking how to implement live update of Xenstore-stubdom.
I should note that my plan is to support live update for a Xenstore PVH
stubdom only, as kexec functionality is much easier to implement for
that case.
The main problem is to transfer the Xenstore state to the new
