title: Migrating from Cake 1.3 to 2.0 and beyond - migrate existing, or only use for new?
body: <p>I'm nearling completion of my first CakePHP-driven website and just saw they're already working on CakePHP 2.0 (not the stable release yet).</p>
  
  <p><strong>My questions:</strong></p>
  
  <ul>
  <li><p>Is it incredibly time consuming to move to a new version of CakePHP (when it becomes the "stable" release that is)?  I know they have migration guides, but - I've never used a framework before, so I've never had to migrate anything.</p></li>
  <li><p>Do you migrate your code for existing projects, or leave it as is and use the new stable version for future projects only?</p></li>
  <li><p>Where can I find what version of CakePHP I currently have installed?  I've looked at the LICENCE and VERSION files, but cannot find the installed/current version listed in them.</p></li>
  </ul>
  
  <p>These seem like simple questions, but I greatly appreciate any thoughts/advice - searching this on Google just brings up how-to-migrate pages, not pros/cons...etc.</p>
