[Kea-users] Kea-upgrading from 2.6 to the latest

[Kraishak Mahtha]

Hi Peter, Thanks for responding. So, basically, I have these doubts
The client-class definition inside the pool was previously one line, now in
the latest version. I see that the client class is a set of ArrayLists, so
can we mention the comma-separated classes,
like let's say I have two pools configured in load balancing mode, where I
want to associate pool-1 with clientclassPhones and pool-2 to associate
with clientclassLaptop can we configure it like below
 "pools": [
            {
                "client-classes": ["HA_dev-ipv4-stack-remote-20",
"clientclassPhones"]
                "pool": "14.0.0.12-14.0.0.19"
            },
            {
                "client-classes": ["HA_kea-dhcp-21", "clientclassLaptop"]
                "pool": "14.0.0.2-14.0.0.9"
            }
        ],
