Upgrading from Bundler 1 to Bundler 2
Your existing applications will continue to use Bundler 1. Bundler will never change your application to a new major version until you choose to do so. If your application is ready, you can upgrade that application to the latest installed version of Bundler by running bundle update --bundler.
We recommend committing your Gemfile.lock before you upgrade. That way, if something goes wrong or doesn’t work, you can always revert to the previous lockfile and go back to using Bundler 1.
