Since Tuleap 10.5, you can move artifacts from a tracker to another one.
To be able to move an artifact:
you must be tracker administrator of both source and target trackers
artifact deletion must be allowed (Siteadmin>Administration>Tracker>ArtifactsDeletion)
However artifacts containing artifact links and artifacts connected to FRS releases cannot be moved.
