I ugraded a container from Debian 9 to Debian 10 and got a new IP4 address

More of an observation than a problem but I ugraded a container from Debian 9 to Debian 10 and got a new IP4 address when running lxc list.

Is this expected behaviour?

Its possible that the DHCP client was changed (perhaps to systemd-networkd?) that uses DUID rather than MAC address as the client identifier, causing a new lease to be allocated.

Interesting… I don’t see why not…
