Upgrading a Rails 6.1 app to Rails 7.0

At my previous client’s project, I got tasked with upgrading their large Rails app version from 6.1 to 7.0.8. It was my first time doing a Rails upgrade, and having benefited from many resources from the community, I wanted to give back by sharing the process.I won’t cover any changes to the asset pipeline here. This app was already running on the latest webpacker version and it wasn’t included in this project.
