title: Switching to new format of upgrade scripts in magento
body: <p>Current version of my extension hosted on magentocommerce is <code>v1.0.0</code>, and right now I have the install script named as <code>mysql4-install-1.0.php</code>. Notice only <code>1.0</code> and not <code>1.0.0</code>.</p>
  
  <p>Now I am about to release a small bug fix <code>v1.0.1</code> and also thought of switching to the new nomenclature of upgrade scripts.</p>
  
  <p>Should I just rename <code>mysql4-install-1.0.php</code> to <code>mymodule_setup/install-1.0.0.php</code> and then add a new <code>upgrade-1.0.0-1.0.1.php</code> under <code>mymodule_setup</code> directory?</p>
  
  <p>How do I make the transition without breaking old installs using it?</p>
