Discovery models and metadata, including indexes and relationships, can be exported into a CAR file like other resources. If you perform an export from Studio, Discovery index and relationship files are not included unless you check the Discovery Files check box in the Export dialog box. When you perform a Full Server Backup, all Discovery resources are exported to the backup file by default.

Exporting and importing resources from Studio is documented in the TDV User Guide. Exporting and importing using the command line is documented in the TDV Administration Guide. The TDV backup_export.sh and backup_import.sh scripts include existing indexes and relationships, as well as models and relationship data, in the CAR file.

Note: When you import a CAR file that contains Discovery index and relationship files, the index status of the imported data sources is updated only if the exported CAR file was created with a 6.1 or later version of TDV server. The index status can be displayed in the Discovery Matrix panel and on the Relationship Discovery tab for an open data source.

To reuse a Discovery model created in a previous release, you must select the Discovery Files option during the Studio export or full server backup. The export/backup archive then includes the Discovery relationships, indexes, and task information. When you import the archive, Discovery relationships, indexes, and task information are imported only if the Discovery Files option is selected at import.

Note: You can reuse a Discovery model created in earlier versions of Discovery except for Discovery models created in 5.2. You must recreate Discovery 5.2 models.
