This card shows how to upgrade a Rails 2 application from Rails 2.3.8 through every single patch level up to 2.3.18, and then, hopefully, Rails LTS. This includes both code snippets embedded in the card text and code that is included as a file attachment.

(For example, this change in Rails 4.1 would have caused us hours of pain if we hadn’t known to watch for it.) But more than that, the upgrade guide will explain you should make those changes.

And that’s important, because it helps you understand which of its suggestions you should follow, and which you can ignore.

In the application’s root folder, edit the Gemfile and change the rails version (in my case from 4.1.4 to 4.1.14): The last command will still show the old version.

We still need to tell rbenv to use the new version. If you're experiencing failures, please revert to the old behaviour by setting: Capybara.configure do |config| config.match = :one config.exact_options = true config.ignore_hidden_elements = true config.visible_text_only = true end If you're migrating from Capybara 1.x, try: Capybara.configure do |config| config.match = :prefer_exact config.ignore_hidden_elements = false end Details here: bundle exec rspec -f d spec/requests/provisioningobjects_/home/provisioningengine/.rbenv/versions/2.2.4/lib/ruby/gems/2.2.0/gems/activesupport-4.1.14/lib/active_support/dependencies.rb:247:in `require': cannot load such file -- test/unit/assertions (Load Error) from /home/provisioningengine/.rbenv/versions/2.2.4/lib/ruby/gems/2.2.0/gems/activesupport-4.1.14/lib/active_support/dependencies.rb:247:in `block in require' The procedure might also work without the gem ‘minitest’.
