Applications are never rolled back to a previous running state if they were
suspended before the upgrade.

+Rollbacks exclusively affect the `FlinkDeployment`/`FlinkSession` CRDs.
+When releasing a new version of your Flink application that updates several

backward compatibility. This means that your updates to
non-FlinkDeployment/FlinkSession resources must be compatible with both old and
new FlinkDeployment/FlinkSession resources.

detect more complex issues.
