[jira] [Created] (KAFKA-15501) Kafka to KRaft combined mode migration v3.5

Ritvik Gupta created KAFKA-15501:
------------------------------------

             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 ?
