Overall

This documents the upgrade from Rails 4.2 to 5.2 through four parts: Backend, Frontend, Infrascture and Checkboxes

Backend

Rails update task

Run rake command rails app:update, it creates a set of new configration files for active storage, action cable, content security policy etc. As we dont use these features, the default ones from code generation are kept.
