------------------------------------------

             Summary: Add documentation on how to upgrade serializers for managed state
                 Key: FLINK-6478
                 URL: https://issues.apache.org/jira/browse/FLINK-6478
             Project: Flink
          Issue Type: Improvement
          Components: Documentation
            Reporter: Tzu-Li (Gordon) Tai
            Priority: Critical
             Fix For: 1.3.0


There needs to be a documentation that explains how to use the new serializer upgrade APIs in {{TypeSerializer}}, and how the methods work with checkpoints. This documentation should probably be placed under "Application development --> Streaming --> Working with State".

Ideally, it should also come with a minimal example for users that perhaps use serialization frameworks that already have built-in backwards compatibility (such as Thrift).
