Wonderful news for anyone looking to migrate to YouTrack!
We continue extending our import capabilities to make migration as smooth and fast as possible. Introducing our new tools for importing from Mantis and Bugzilla issue trackers. You can now either import a specific project with all the issues it contains, or import all projects at once. Mantis sub-projects are also supported via YouTrack custom fields. Visit our Tools page to learn more and download the scripts.
Migrate with pleasure!
