Hi, I can see in V2.4.0, we upgraded zookeeper from 3.4.14 to 3.5.5. So, I guess before V2.4.0 is good to go since it's just zookeeper minor version upgrade. But you still need to have a complete test for the upgrade.
In your case, I think you can expect the new feature: KRaft mode, to remove zookeeper. FYI ref: https://github.com/apache/kafka/blob/trunk/config/kraft/README.md Thanks.
