title: How to upgrade Magento when the database structure changes between versions?
body: <p>All of the upgrade methods I have seen (not sure about the magento connect method) do not touch the database only the files and &amp; directories).  I am on my first Magento build but I see that they have changed the directory structure with past updates.  So my question is how should I update Magento to ensure the database gets upgraded?</p>
