title: SonarQube - How to change severity of mulitple rules in bulk
body: <p>I want to change the severity of mulitple rules in a quality profile in bulk. At the moment there are ca. 20 rules with "Blocker" severity and I want to set them all to "Critical". Because we created a new quality gate for blocker rule violations and this rules should not be included.</p>
  
  <p>I could do this manually one by one. But I wonder if it's possible to do it in bulk. With 20 rules it's just annoying, with 100 rules changing the severity manually one by one would be a major headache.</p>
  
  <p>There's an issue about this, <a href="https://jira.codehaus.org/browse/SONAR-3421" rel="nofollow">SONAR-3421 "Enhance Bulk Change possibilities for Profile Rule Filter"</a>. The issues is closed now. But as far as I can tell, this functionalty has not been implemented.</p>
