[jira] [Created] (KAFKA-15381) Controller waiting for migration should only allow failover when transactions are supported

David Arthur created KAFKA-15381:
------------------------------------

             Summary: Controller waiting for migration should only allow failover when transactions are supported
                 Key: KAFKA-15381
                 URL: https://issues.apache.org/jira/browse/KAFKA-15381
             Project: Kafka
          Issue Type: Bug
            Reporter: David Arthur
             Fix For: 3.6.0


After a KRaft controller starts up in migration mode, it enters the "pre-migration" state. Unless transactions are supported, it is not safe for the controller to fail over in pre-migration mode. This is because a migration could have been partially committed when the failover occurs.
