> This issue tracks the implementation of backwards compatibility between Flink 1.1 and 1.2 releases.
> This task subsumes:
> - Converting old savepoints to new savepoints, including a conversion of state handles to their new replacement.
> - Converting keyed state from old backend implementations to their new counterparts.
> - Converting operator and function state for all changed operators.
> - Ensure backwards compatibility of the hashes used to generate JobVertexIds.
