For each DHCP interface in the header of the static mappings underneath the main settings I believe.

For anyone needing to migrate static mappings (especially DHCPv6), I put together a small offline converter that takes an exported config.xml and copies ISC static mappings into the Kea sections (v4 + v6).

Important notes:
Kea subnets still need to be created first in the GUI so the tool can map reservations to the correct subnet UUIDs.

Kea does not need to be enabled yet, you can import the converted config, review reservations in the UI, and only switch services when you're happy.

As always: take a backup / snapshot first.

The tool works on exported XML only and never touches the live system.

I originally wrote it for a client migration, but if others want to test it, I'm happy to share it.

Feedback welcome, especially for IPv6 and multi-VLAN setups.
