             Summary: Kafka to KRaft combined mode migration v3.5
                 Key: KAFKA-15501
                 URL: https://issues.apache.org/jira/browse/KAFKA-15501
             Project: Kafka
          Issue Type: Improvement
          Components: controller, kraft
            Reporter: Ritvik Gupta


This is regarding the 
[KIP-866|https://cwiki.apache.org/confluence/display/KAFKA/KIP-866+ZooKeeper+to+KRaft+Migration]
 KRaft migration steps for {*}Kafka v3.5.1{*}.

We want to migrate our Kafka ZK mode cluster to KRaft mode and are following 
the steps mentioned 
[here|https://cwiki.apache.org/confluence/display/KAFKA/KIP-866+ZooKeeper+to+KRaft+Migration#KIP866ZooKeepertoKRaftMigration-MigrationOverview]
 for separate KRaft brokers and controllers migration.

As mentioned in the KIP-866, currently the [combined mode 
migration|https://cwiki.apache.org/confluence/display/KAFKA/KIP-866+ZooKeeper+to+KRaft+Migration#KIP866ZooKeepertoKRaftMigration-CombinedModeMigrationSupport]
 is not supported and is only suitable for dev environments, but we want to 
utilize *combined mode* for our production environments and continue with our 
current set of broker machines ( as otherwise we would need to provision 
additional controller node machines ).

By which version can we expect the *KRaft combined mode* migration be available 
?
