Dear Kafka Community, We are upgrading our kafka instance from 2.8.1 version to 3.5.2. The setup we have was of 3 kafka broker nodes and 3 zookeeper nodes. We performed a rolling upgrade of the broker with the 3.5.2 version and observed that some topics got deleted post upgrade. we don't see any logs related to the topic's deletion. All the topics have the same configuration.
Has anyone faced similar issues while upgrading kafka? Could you please help in troubleshooting this issue? Thanks Sai.
