Hi,

I would recommend you to check the release notes of 1.14[1] and 1.15[2]. If
your Flink jobs are using Flink features that have big improvements in
these two releases, it would be better to upgrade step by step without
skipping 1.14.x.

In general, depending on how complicated your jobs are, it is always a big
challenge to upgrade Flink with skipping version(s), i.e. it is recommended
to upgrade constantly following the Flink release period.

Best regards,

In addition to the state compatibility mentioned above, the interfaces
provided by Flink are stable if they have public annotation[1]

Hi, Alexey.
You could check the state compatibility in the compatibility table.
The page includes how to upgrade and whether it is compatible among
different versions.
