title: 2 instances of Sonar on same machine
body: <p>Can we run 2 instances(2 different versions) of Sonar on same machine?</p>
  
  <p>At present Sonar 3.7.3 is installed and is been used with Hudson for Sonar Reports.
  Now, there are some projects that run on Java 8 and Java 8 is not supported by 3.7.3 Sonar version.</p>
  
  <p>So to run the Java 8 projects, I need to use the latest version of Sonar but upgradation of Sonar would impact the existing projects that run on Java 6.</p>
  
  <p>So can we configure 2 Sonar instances and can configure Hudson accordingly so that both the java 6 and java 8 projects can be run for Sonar reports?</p>
