Run bundle update cucumber capybara cucumber-rails to update to the newest versions.

Backup your features/support/path.rb to be able to add your own paths again after the cucumber installation script in step 4.

Backup your features/support/env.rb file to be able to reintegrate parts like your blueprints setup:

ENV["RAILS_ENV"] ||= "cucumber"
require File.expand_path(File.dirname(__FILE__) + '/../../config/environment')
require 'spec/support/blueprints'

Run $ rails generate cucumber:install --capybara to integrate cucumber/capybara into your rails project.

Run your tests and fix error messages by reintegrating parts from your backed up files.
