@X-czh I assume we have generated reference data for state migration tests based on 20. Do any of these work when going to v2? Or does the Kryo v2 ->v5 effect a large number of these tests?

[X-czh]

@davidradl All except the Kryo ones work. The Kryo related tests have been intentionally disabled in #26243 (see the comments in KryoSerializerUpgradeTest for more details) and will be reenabled again in #26443 (only testing migration starting from v2.0).
