> @kurtostfeld I see your motivation for doing this, but you mention that there will not be binary compatibility with v1 state. Do you have an idea on how v1 Kyro state would migrate to v2 state after this fix? We are trying to encourage v2 migration - and this could be a big inhibitor. @davidradl Sharing this info in case it helps answer your question. @kurtostfeld can correct me if I mistate anything. The original Pull Request, which was documented in this [FLIP-317](https://cwiki.apache.org/confluence/display/FLINK/FLIP-317%3A+Upgrade+Kryo+from+2.24.0+to+5.5.0) provided code to migrate older state forward. But there was some email discussion about keeping the Kryo upgrade for Flink 2.x. Because of this, there was another merge request created that was simpler and did not include the backwards compatibility. I think either Pull Request could work, but we just need someone to decide and approve before things get too stale. This [Jira ticket](https://issues.apache.org/jira/browse/FLINK-3154) has more discussion in the comments.
