As was suggested to you by other posters, please read the upgrade guide carefully (here is the official one http://edgeguides.rubyonrails.org/upgrading_ruby_on_rails.html)
it is recommended that you have very good test coverage before you begin.
I suggest you use a tool like simple-cov to make sure all your lines of code are tested before you begin, as well I'd recommend integration coverage for every major end-user "happy path" through your app.
When you are sure you have complete test coverage, change the version in the Gemfile and then run "bundle update rails"
