Installing ELK7 - Configuration changes

Hi Guys,
we are working with ELK 6.8.1 until today. we are going to install a fresh ELK7 with fresh and clean.
i understand that the cluster configuration changed.
Please see the configuration that i have on my master in 6. what should i change?
should i remove this from 7?
discovery.zen.ping.unicast.hosts: ["192.168.11.3", "192.168.11.4"]

what should i add instend of this?

This is the new equivalent setting: discovery.seed_hosts: ["192.168.11.3", "192.168.11.4"]

thank you. @pmusa and what is this?
cluster.initial_master_nodes:

you can find a lot of info in the docs :slight_smile:

As your cluster is already running, you should not worry about it.
