title: How do I upgrade SQL Server localDB to a newer version?
body: <p>Is it possible to upgrade SqlServer localDB from 2012 to 2014?</p>
  
  <p>We currently use version 11 from SQL Server 2012.  I need to upgrade to version 12 from SQL Server 2014.  </p>
  
  <p>I would like to be able to do it without losing my tables and data.</p>
  
  <p>I installed a new localDB but I then I don't have my data.  It also has another name and I can't really change the config files since it's a team project.</p>
  
  <p>I tried using the command line sqlLocalDB tool to create a 2014 version called v11.0 but it created it in the old 2012 version any way.</p>
  
  <pre><code>C:\Program Files\Microsoft SQL Server\120\Tools\Binn&gt;sqllocaldb create v11.0
  LocalDB instance "v11.0" created with version 11.0.3000.0.
  
  C:\Program Files\Microsoft SQL Server\120\Tools\Binn&gt;sqllocaldb create v12.0
  LocalDB instance "v12.0" created with version 12.0.2000.8.
  
  C:\Program Files\Microsoft SQL Server\120\Tools\Binn&gt;sqllocaldb create aaaaa
  LocalDB instance "aaaaa" created with version 12.0.2000.8.
  </code></pre>
  
  <p>Why would naming it v11.0 change which version was used?</p>
  
  <p>How can I upgrade the existing v11.0?</p>
