title: SQL Server 2008R2 Express and LocalDB on same machine
body: <p>I am trying to evaluate LocalDB. My computer already has SQL Server 2008 R2 Express on it (in addition to SQL Server 2008 R2 Standard and SQL Server 2008 Standard).</p>
  
  <p>When I try to install LocalDB, it asks for confirmation to upgrade. So it is trying to upgrade by 2008 R2 Express to Localdb? And I hit no and didn't proceed further.</p>
  
  <p>Can someone please point me to links where they explain what exactly happens? Will my 2008 R2 Express be gone forever? All databases will be upgraded to LocalDB? There will not be a Express service anymore?</p>
  
  <p>I just want to use localdb as an addition, not as a replacement. Is this possible?</p>
