title: Eclipse IDE upgrade from Kepler to Luna went very bad
body: <p>I upgraded my Eclipse IDE for Java developers from Kepler to Luna using the <strong>worst</strong> possible upgrade feature of Eclipse and it messed up my current workspace totally.
  I added the update site for Luna - <a href="http://download.eclipse.org/eclipse/updates/4.4" rel="nofollow">http://download.eclipse.org/eclipse/updates/4.4</a>
  and selected all and installed.
  Then it took an hour to figure out the conflicts and finally when it installed, my Eclipse is behaving very erratic.</p>
  
  <ol>
  <li>I can see welcome screen changed and couple of new menu items.</li>
  <li>Eclipse market place is gone, I don't know how to get it back.</li>
  <li>Intermittent freezes forcing me to restart.</li>
  <li>My Grails setup is gone and I can't install from Market was gone.</li>
  </ol>
  
  <p>Can anybody suggest what is the right procedure to upgrade? (I read the wiki and it doesn't work) and I am looking for methods that actually worked for you.</p>
  
  <p><em>These are the times I some times cringe in pain and crave for a managed or paid IDE, as a simple task like "upgrade" should be so damn easy and click of a button"</em></p>
