=> BTW this is an easy case because you can infer from the address in
what subnet a reservation should go. But of course when you have no address
i.e. when a reservation is used to set hostname and/or specific options,
you can only rely on a heuristic in particular when you can't use global
reservations (e.g. when you use an old Kea version which does not support

PS: teh Kea Migration Assistant is available in the public repository and
should be integrated into the distribution of the next ISC DHCP.
You can get soem idea from it and of course if you can propose improvements
you are welcome.
