title: Updating Rails 3.0.3 to 3.0.5
body: <p>I don't have any experience in updating a Rails app and when I google it, it shows only complex ways how to update Rails 2.x to 3.0.x. So my issue is a bit simpler.</p>
  
  <p>So far I tried this:</p>
  
  <ol>
  <li>Edited the Gemfile and change to 3.0.5</li>
  <li>bundle install</li>
  </ol>
  
  <p>Then in the related gemset you see all rails 3.0.5 and 3.0.3 gems.</p>
  
  <ol>
  <li>Is this the usual way?</li>
  <li>Should I remove all 3.0.3 gems?</li>
  <li>Is there a better way to update a rails app?</li>
  </ol>
