Import from Other Trackers
If you have an existing JIRA installation (up to version 4.x), consider importing your JIRA projects to YouTrack.
Just get a YouTrack plug-in for JIRA, choose a project and types of bugs to import, and make your issues available from YouTrack. You can import issues along with groups, roles, and group memberships, meaning that your users will be able to log into YouTrack with their existing JIRA credentials.
If you choose to work with JIRA and YouTrack concurrently, you can update issue changes from JIRA to YouTrack at any time.
