tvielgouarin commented on issue #7604: [Flink 11249] FlinkKafkaProducer011 can not be migrated to FlinkKafkaProducer URL: https://github.com/apache/flink/pull/7604#issuecomment-459650287 So I tried to migrate a job with a `FlinkKafkaProducer011` to a `FlinkKafkaProducer` locally by using a a flink version built from @yanghua PR. And the Exception `org.apache.flink.util.StateMigrationException: The new state serializer for operator state must not be incompatible` still persist. So I guess this PR doesn't totally fixes the issue.
