title: Upgrading Magento from 1.1.8 to 1.5 stable
body: <p>Am looking to upgrade Mangeto from version 1.1.8 to version 1.5.</p>
  
  <p>This is a quite a leap I am taking I know, but and I have tried the following already (as some one else had suggested on another site):  </p>
  
  <ul>
  <li>dump v1.1.8 database, restore it in a new database.  </li>
  <li>install magento 1.5 pointing on the restored v1.1.8 database  </li>
  <li>let the upgrader run  </li>
  <li>add the old theme files  </li>
  <li>test that it all works.</li>
  </ul>
  
  <p>When doing that, the upgrader kept saying some tables already existed.</p>
  
  <p>Can anyone help me out?</p>
  
  <p>Thanks</p>
