title: upgrading from sql server 2008 to sql server 2008 R2
body: <p>I thought R2 is a patch/service pack. I've been looking for a download but dont see one. I assume therefore that R2 is a new version, and that I would need the install media for sqlserver 2008 r2 to do an upgrade?</p>
  
  <p>Also, would I need to pay for new licenses?</p>
