Following https://kafka.apache.org/documentation/#kraft_zk_migration 1) It completely skips the facts that the storage for the new quorum should be formatted using the existing cluster id. 2) In Provisioning the KRaft controller quorum: controller.quorum.voters=1@localhost:9093 should be controller.quorum.voters=3000@localhost:9093 as node.id=3000 3) When migrating brokers, it states: # Don't set the IBP, KRaft uses "metadata.version" feature flag # inter.broker.protocol.version=3.4 # Keep the migration enabled zookeeper.metadata.migration.enable=true # Remove ZooKeeper client configuration # zookeeper.connect=localhost:2181 However if I do that, my brokers fails to restart and print: org.apache.kafka.common.config.ConfigException: If using zookeeper.metadata.migration.enable in KRaft mode, zookeeper.connect must also be set. 4) When disabling zookeeper.metadata.migration.enable or keeping zookeeper.connect to get past this step, when brokers restart they print a lot of error messages: org.apache.kafka.common.errors.InvalidRequestException: Received request api key LEADER_AND_ISR which is not enabled [2023-02-08 12:06:25,776] ERROR Exception while processing request from 192.168.1.11:9092-192.168.1.11:57210-107 (kafka.network.Processor) -- This message was sent by Atlassian Jira (v8.20.10#820010)
