About This Episode

Ever wanted to run your Rails app against multiple versions of Rails? You can with "dual booting" which helps you keep your stable Rails version but also test against the latest.

Notes

Rails 6.1.0.rc1 was just released which means we will be upgrading our Rails apps very soon!

Upgrading Rails can be tough, that's why it can be super useful to dual boot your Rails app against two versions. This allows you to work on your app like normal but also keep an eye on your code's compatibility with the next version of Rails. This way you can be ready for an easy upgrade to the next version.
