Hi All, We have an application with 2 sliding windows. We are doing checkpoint and savepoint to s3 bucket. Now we added one more sliding window. When we deploy with restore from savepoints enabled, we are getting below error.

the new state serializer (org.apache.flink.api.java.typeutils.runtime.PojoSerializer@7a86da3d) must not be incompatible with the old state serializer (org.apache.flink.api.java.typeutils.runtime.kryo.KryoSerializer

Can someone tell how we can restore from savepoints when there is any state change ?
