title: How to update the JHipster project after updating JHipster generator?
body: <p>I updated my JHipster installation as per this <a href="http://jhipster.github.io/2014/02/19/jhipster-release-0.11.0.html" rel="noreferrer">page</a> by running the command </p>
  
  <pre><code>npm update -g generator-jhipster
  </code></pre>
  
  <p>But to update my application I am not sure where should I run the next command <code>yo jhipster</code>.</p>
  
  <p>I tried running it from the root of existing project, but it asked me to enter the name of the new project. </p>

  <p>I tried running it at one level above the root of existing project, then also it asked me the name of the new project. But this time I entered the same name and the jhipster generation process ran. However there was no change in any of the major files like package.json or Gruntfile.js or bower.json</p>
  
  <p>What is the correct way to update a JHipster project, once the JHipster generator is updated?</p>
