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.
