title: migrate from grails 3.0.4 to 3.0.6
body: <p>What is the simplest way to migrate a Grails app developed in 3.0.4 to 3.0.6? </p>
  
  <p>The grails documentation recommends to create a new app and migrate every component one by one. But there should be a simple way if we are migrating within version 3?</p>
  
  <p>Any help much appreciated</p>
