title: Joomla, move whole site to different domain name
body: <p>I have a website built in joomla and it is live on the web at a url:</p>
  
  <p><code>http://oldsite.com</code></p>
  
  <p>I have been asked to move it to another url - domain name</p>
  
  <p><code>http://newsite.com</code></p>
  
  <p>How should I do this correctly without messing up the site and joomla installation?? </p>
