the savepoint problem of upgrading job from blink-1.5 to flink-1.10

[Roc Marshal]

Hi, all.


When using savepoint to upgrade a Flink job from blink-1.5 to flink-1.10, 
the system prompts that blink savepointV3 is incompatible with the version in 
Flink. Is there any solution? 


Thank you so much.
















Sincerely,
