[Kea-users] kea-dhcp upgrade from 2.6.4 -> 3.0.3

[Peter Davies]

Hi Ronald,

    The Kea 3.0.0 Release Notes contain the following information 
regarding the
deprication of the Kea Control Agent (CA).

—-PASTE—-
  1. **Native HTTP/TLS support**: The DHCPv4, DHCPv6, and DHCP-DDNS
daemons now have native support for API sockets over HTTP and TLS
(HTTP), without the need to use the Control Agent (CA). This greatly
simplifies the configuration as CA is no longer necessary [#3477, #1764,
#3490]. As a result, the CA is now deprecated.
—-PASTE—-

The Stork 2.4.0 Release notes contain the following information 
regarding the
deprication of the CA.

---PASTE---
1. **Direct API support for Kea**: The Kea Control Agent (CA) is
deprecated as of Kea 3.0; it is now possible to run Kea in a mode where
the DHCP daemons receive commands directly (without the CA). This caused
a major refactoring of Stork: the application concept was dropped and
Stork now operates on the daemon level [#1835, #2193]. We fixed a
problem where the Stork agent was not able to detect a Kea instance when
the control agent was bound to an IPv6 address [#2092]. System tests for
the direct API were implemented [#2133]. Commands to Kea are now sent
over other control sockets if the first one is unavailable [#2223]. The
daemons are no longer removed from the database if they are inactive; a
button can delete them manually [#2095]. The agent can now communicate
to UNIX control sockets if they are configured by name only in Kea
[#2166].
---PASTE---

See: https://downloads.isc.org/isc/kea/3.0.0/Kea-3.0.0-ReleaseNotes.txt and
https://downloads.isc.org/isc/stork/2.4.0/Stork-2.4.0-ReleaseNotes.txt

If there are duplicate entries, you should stop and disable the CA.

When the CA is no longer running, you should be able to remove the 
daemon, which
communicates over the CA.
