What is the official migration way from ISC to Kea?

[opnsense-user123]

I typically ask more questions here than answer them, so take any of this below as half 'tip' and half question (as in, am I correct about what I'm saying?).

I just made the swtich on my 25.7.11_9 system. I have three LANs so I thought I'd try one or two before changing the final one that has many more hosts on it. That was unsuccessful because, even though in ISC DHCPv4 config I unchecked the box for those two LANs, ISC seemed to still be bound to port 67 on those LANs. So I had to do all three at once and make sure ISC was really stopped.

Then I noticed in the Kea error logs that the "Control Agent" is deprecated. So though I at first checked the box to turn it on in that page, I later went back and turned it off.

It was easy to export a CSV fie of the reservations from ISC, one for each LAN. I could import those into Kea after I created the three LANs in the Subnets tab (after having of course selected the three interfaces in Settings > General > Interfaces). Reservations should be within the subnet (obviously) but outside the 'pool' allocation.

I'm using the default of raw sockets and did check the box to create standard firewall rules for communications.

I did not have to reboot.

I'm not seeing errors in the Kea log and I am seeing hosts starting to appear in the 'Leases DHCPv4' panel. Early going, but so far so good. Hoping for a smooth update to v26 when the openssl patch comes out which I'm hoping is soon.

That is as expected.

Only needed for HA setups! ;)
