If you're migrating from Jira Server to Jira Data Center, please follow the instructions below to migrate your Structure configurations and all your structures:

This is the easiest way to migrate to DC. If you've installed a DC instance on the same hardware as your Server instance, the Structure software and all your structures should already be there (Structure and all extensions data is stored in the Jira database).

Migration is available for Structure and Structure.Gantt, and any other extensions (Pages, Deliver, etc.) will be included in the backup.
