Hello, For upgrading jobs between Flink versions I follow the guide in the doc here: https://ci.apache.org/projects/flink/flink-docs-release-1.7/ops/upgrading.html#upgrading-the-flink-framework-version
It states that we should always use savepoints for this procedure, I followed it and it works perfectly. I just would like to know if there is a reason why is not advised to use checkpoints for this procedure. Say for example that the job has externalized checkpoints with RETAIN_ON_CANCELLATION policy, one could cancel the job before the upgrade and use the retained checkpoint to restart the job from it once the Flink cluster is upgraded... or maybe I'm missing something ? I performed some tests and we are able to upgrade using checkpoint, by passing the checkpoint path in the "flink run -s" parameter. Could you help to clarify if this is advised (and supported) or we should stick to the use of savepoints for this kind of manipulations ? Thanks in advance for your help.
