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.
