Till Rohrmann commented on FLINK-10490:
---------------------------------------
Is there any downside of using {{SavepointV2Serializer}}? If not, then I would
suggest to immediately upgrade this.
> OperatorSnapshotUtil should probably use SavepointV2Serializer

> Reporter: Stefan Richter
> Priority: Major
>
> {{OperatorSnapshotUtil}} is used for testing savepoint migration. This
> utility internally still uses {{SavepointV1Serializer}} and I would assume
> that it should use {{SavepointV2Serializer}}. I wonder if that means that
> some newer cases are actually not covered in the migration tests.
