title: Any quick ways to downgrade Visual Studio Ultimate/Enterprise edition to Professional?
body: <p>I have Visual Studio Ultimate/Enterprise installed from a previous engagement. I've now started at a new place who only have licenses form VS Professional. So I need to downgrade but the supported route involves full uninstall and full reinstall which is obviously rather time consuming.</p>
  
  <p>Are there any "clever" (probably unsupported) ways to do the downgrade?</p>
