You can now upgrade existing applications to new Apache Flink versions in Amazon Managed Service for Apache Flink using in-place Apache Flink version upgrades. With in-place Apache Flink version upgrades you retain application traceability across Apache Flink versions including snapshots, logs, metrics, tags, Flink configurations, resource limit increases, VPCs, and more. You can upgrade to new Apache Flink versions by selecting the application, the snapshot you want to restore from, and the new Apache Flink runtime you require using the AWS CLI, SDK, CloudFormation, or Management Console.
