Kafka Rolling Update Inter Broker Listener

Question

When migrating from one inter.broker.listener.name to another broker by broker, what does happen to the inter broker communication during the time where the brokers in the cluster have a different inter.broker.listener.name configured?

Let's assume:

• Broker 1 & 2 use inter.broker.listener.name "internal"
• Broker 3 uses inter.broker.listener.name "external"

Will Broker 1 & 2 know how to connect to Broker 3 and vice versa / aka is a rolling update possible? If so how does it work (at a high level)?
