Hi Philip,
    It is excellent to hear you are trying to help users migrate to Kea.

You should be able to add the "renew-timer" parameter globally and within a
subnet definition. The following is an example of this:

"subnet4": [{
      "id": 1,
      "subnet": "10.0.1.0/24",
      "renew-timer": 1000,
      "pools": [ { "pool": "10.0.1.1-10.0.1.200" } ] },{
      "id": 2,
      "subnet": "10.0.2.0/24",
      "renew-timer": 2000,
      "pools": [ { "pool": "10.0.2.1-10.0.2.200" } ]
}],

There is no equivalent to ISC DHCPD's  "always-broadcast" keyword. 
Localnet dhcp
traffic processing can be enabled for an interface by setting the 
"dhcp-socket-type"
to  "raw". For example:

"interfaces-config": { "interfaces": [ "eth0" ], "dhcp-socket-type": 
"raw" },

The "authoritative" setting can be specified in global, shared-network, 
and subnet
configuration scopes and is automatically inherited from the parent 
scope, if
not specified.

To allow multiple reservations for the same address, you will need to 
set the
global parameter "ip-reservations-unique" to false; the default is true.

         "ip-reservations-unique": false,

Let us hear how you get on.

Kind Regards Peter
