We strongly recommend that you evaluate YouTrack Daring in a test environment, since you will not be able to revert to YouTrack 1.0 other than by rolling back to a pre-upgrade backup of your database and losing your progress along the way.
If you want to integrate YouTrack Daring with JIRA 4, download JIRA 4 integration plug-in and deploy it to
WEB-INF\lib directory of your JIRA installation. Integration with JIRA 3.x is supported out of the box.
