Hello,

Here is the scenario. We have a kafka/zookeeper ensemble, where kafka and
zookeeper are installed on the same node (instance). There are three zk
nodes and two kafka nodes. In other words, out of the three zk nodes, kafka
is present in two.

Now, these two kafka brokers are in different AZ in AWS. We want to move
them into the same AZ to reduce cross AZ data transfer chatter and
consequent AWS bill.

>From my Google searches, most of the migration stories are related to
migrating from zookeeper to kraft and cluster expansion. However I was not
able to find anything that matches my requirements. If this was simply
kafka brokers, I probably would have created another server in the same AZ
and stopped the one that is running in the different AZ. But having
zookeeper in the same instance doesn't help here.

Does anyone have any pointers/documentation/tutorial on how I should tackle
this? Anything would be much appreciated.

Thanks,
