I made a bad sonar upgrade from 3.4.1 to 3.7.2. I did not upgrade plugins first, and directly upgrade sonar to 3.7.2. After that I found sonar cannot be started due to plugin consistency issue. I removed all plugins and restart sonar. Sonar started normally, but all quality profile rules are empty now, even after I re-installed all plugins from upgrade center. Any ideas?
Best Regards,
