title: Can I install SQL Server alongside SQL Server Express?
body: <p>I already use a third party application that uses SQL Server Express 2008 as a backend, and thus, installs it onto my PC (Windows 7 Ultimate).</p>
  
  <p>I need to do development work against SQL Server 2012 Web Edition, and so, need to install it onto my PC. Will this cause any conflicts with the app that depends on SQL Server Express? Do I have to migrate data from the SQL Server Express install to SQL Server 2012? (I'm worried that might break stuff since I have no control over the application that uses it.)</p>
