docs: The Quality profiles created by users should be renamed when they have the same name
  as the built-in profile to be persisted.
  <p>
  When upgrading from < 6.5 , all existing profiles are considered as "custom" (created
  by users) because the concept of built-in profile is not persisted. The "Sonar way" profiles
  are renamed to "Sonar way (outdated copy) in order to avoid conflicts with the new
  built-in profile "Sonar way", which has probably different configuration.
