You may notice some ghost cards on your story map after having imported from Jira, or when updating epic links. Ghost cards look like this:
Ghost cards are merely a placeholder for when the hierarchy isn't available to place a story or a step. When you initially import from Jira, we recommend trying to get your journey and step backbone in order fairly early, enabling you to move stories into their relevant hierarchy and remove ghost cards.
Try to use Avion if you need to manipulate your backbone structure
If you update epic links in a Jira classic project and Avion cannot map the change to an existing card in Avion, a ghost card will be used. Try to use Avion if you need to manipulate your backbone structure as the tool is well equipped for this. The epic links in Jira are useful as a reference, but Avion provides a much more visual approach to re-ordering journeys, steps and stories.
