### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version I'm trying to downgrade from 3.0.2 to 2.10.4 ### Minimal reproduce step I'm using Kubernetes and I've deployed Pulsar with Helm. Pulsar works fine with 3.0.2 but I want to try the procedure to downgrade to check if it possible to go back to 2.10.4 (in case of emergency). ### What did you expect to see? I expect that Pulsar downgrade works ### What did you see instead? Bookkeepers cannot start and from the logs I see: java.io.IOException: Error open RocksDB database Caused by: org.rocksdb.RocksDBException: **unknown checksum type 4** in /pulsar/data/bookkeeper/ledgers/current/ledgers/000006.sst offset 929 size 32 ### Anything else? Zookeeper and brokers seem to run correctly ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
