And to answer the second point. The failover protocol is not guaranteed
to be compatible between different versions, so you need to upgrade
both pretty much at the same time. A few minutes difference is probably
going to be ok.
If you wish
to use the failover protocol, make sure that both failover
peers are running the same version of the ISC DHCP server.
