Migration to Kafka4

Hi,

  Are there any technical documentation/case study available for migrating from 3.x to 4.x, other than the HELP documentation.

Thanks,
Sachin Jangle.

Not sure if this helps, but one of the main aspects is moving from ZooKeeper to Kraft, we have a blog on how we do it here: https://www.instaclustr.com/support/documentation/kafka/useful-concepts/zookeeper-to-kraft-migration-process/
