Rails 6.1.7 -> 7.0.4 にあげてみました ただし、ほぼ api mode で使っていたものです
Ruby は 3.1.2 を使っています

Rails アップグレードガイド - Rails ガイド をよく読みます

Gemfile の rails を 7.0.4 にして bundle update rails をします

After this, check Rails upgrade guide at for more details about upgrading your app.


config/initializers/new_framework_defaults_7_0.rb は読んで不要だったら消します
config/application.rbconfig.load_defaults 7.0 に変えます


bundle exec rubocop -a

bullet のエラーがでたので直したのがほとんどです

念のため development mode、production mode で動作確認してみて終わりです
