title: Magento update from 1.4.2 to 1.7
body: <p>I have problem with update magento 1.4.2 to 1.7. When I try to use <code>./pear list-upgrades</code>, I get the message of not having any upgrades at the moment.</p>
  
  <p>Am I missing anything ? </p>
  
  <p>And when reading tutorial on the net, they use <code>./mage</code> which is a replacement for <code>./pear</code>, where can I get it and can I use it for the current version of Magento ?</p>
  
  <p>Thanks,</p>
