title: Upgrade PHP from version 5.2 to 5.3
body: <p>I've been using PHP version 5.2 and now need to upgrade to version 5.3 (Windows/Apache).  I have been using 5.2 for awhile now and have customized many things in php.ini and added some extra extensions.</p>
  
  <p>How can I upgrade to version 5.3 without having to reconfigure everything?  Or does upgrading require that I customize my PHP installation all over again?</p>
  
  <p>Thanks, Brian</p>
