I have a kafka cluster with 6 brokers and over 60 topics, with a replication factor of either 2 or 3. We plan to replace all the existing brokers with new nodes.
I have 2 questions: i) once we add 6 new nodes to the cluster making it total 12 nodes, and shut down old brokers one by one, will the topics move to new brokers automatically? ii) If not, we will have to move them using the reassignment tool, in that case do we need to '__consumer_offsets' topic as well, or kafka will take care of that itself?
