title: How to upgrade to symfony2.3 from symfony2.1.7, can not find correct composer.json dependencies?
body: <p>I am trying to upgrade from Symfony2.1.7 to Symfony2.3 stable release. I am using <code>php composer.phar update</code> But I am facing package dependency problems. Below is link to my composer.json and the command line output.</p>
  
  <p><a href="https://gist.github.com/deepak-kumar/5785254" rel="nofollow">composer.json</a>  And <a href="https://gist.github.com/deepak-kumar/5785258" rel="nofollow">command line output</a></p>
  
  <p>After looking at the output I can see friendsofsymfony/user-bundle dependency</p>
  
  <pre><code>friendsofsymfony/user-bundle 2.0.x-dev requires symfony/security-bundle &gt;=2.1,&lt;2.3-dev
  </code></pre>
  
  <p>And something similar for sonata-project/user-bundle</p>
  
  <pre><code>- symfony/framework-standard-edition 2.3.x-dev requires sonata-project/user-bundle dev-master -&gt; satisfiable by sonata-project/user-bundle[dev-master].
  - sonata-project/user-bundle dev-master requires friendsofsymfony/user-bundle 1.3.* -&gt; satisfiable by friendsofsymfony/user-bundle[1.3.x-dev, v1.3.0, v1.3.1, v1.3.2].
  - sonata-project/user-bundle dev-master requires friendsofsymfony/user-bundle 1.3.* -&gt; satisfiable by friendsofsymfony/user-bundle[1.3.x-dev, v1.3.0, v1.3.1, v1.3.2].
  </code></pre>
  
  <p>So seems it needs <code>symfony/security-bundle &gt;=2.1,&lt;2.3-dev</code> but I want it to be 2.3 or above is it like I can not upgrade with these bundle.</p>
  
  <p>Can someone guide me in right direction, If I am missing something?</p>
