------------------------------------
Summary: Create a migration e2e test
Key: FLINK-25752
URL: https://issues.apache.org/jira/browse/FLINK-25752
Project: Flink
Issue Type: Improvement
Components: Stateful Functions
Reporter: Igal Shilman
A separate e2e migration test is needed that verifies that a save point taken
with prior statefun versions is successfully opened in the current version.
We need this test to run within its own migration profile, that includes at
least a Kafka ingress/egress pair.
It can be completely based remote functions, without any verification/failure
injection aspects to it, and this probably should be based on
{{testcontainers}} instead of the harness.
having test containers will allows the test to create a save point in an
arbitrary previous version (say 3.1.1)
based on the previously released official docker images, and load it with the
current version.
The test would be bit more time consuming, and that's why I would recommend
that to run under a different profile.
