Sorry to jump into the thread :), but we're planning on upgrading a
failover pair from dhcpd 4.1.2 to 4.2.3 soon, and I've been trying to
determine if we can upgrade one half at a time, or if we have to upgrade
them both at the same time. Failover compatibility between versions
doesn't seem well documented, at least I haven't found any.
Can one half of a failover pair run 4.1 and other other 4.2 for a short
interval without breaking things horribly?
