The page gives no date for this.",
  "migration_path": "1. Upgrade the MSK cluster to the recommended Kafka version or a higher version before the end of support date. The recommended version is marked in [Supported Apache Kafka versions](https://docs.aws.amazon.com/msk/latest/developerguide/supported-kafka-versions.html).\n2. Before upgrading, verify that the version of your client-side software supports the features in the new Kafka version. Server-side upgrades do not automatically update client applications.\n3. Follow [Upgrade the Apache Kafka version](https://docs.aws.amazon.com/msk/latest/developerguide/version-upgrades.html) to upgrade with the console, the AWS CLI or the API. The CLI command `aws kafka get-compatible-kafka-versions` lists the versions the cluster can upgrade to.\n4. Version downgrades are not supported.\n5.
