I'm going to ES of my application (it's large) from version 5.3 to 7.7
I have to fix my application codes, finding difference between the two versions.
Elastic documentation has many
Breaking changes pages, corresponding to every minor upgrades (not only every major upgrades).
So do I have to check all the breaking changes pages (5.4, 5.5, ... 7.6, 7.7) and find where to fix in my application?
Or is there more easy way to find all the differences between 5.3 and 7.7?
