It is possible to migrate Objects from one instance to another using Import/Export Utility. Once Elements in staging environments are ready for production you can export/

NOTE:
- Dependent Portal Page Layouts, Templates, and Assets will be added to Export automatically.
- For Portal Page code iteration, it is recommended to upload new Portal Page Assets rather than 
Here’s the uniqueness checking algorithm: - The Utility checks the source_nameandsource_idof all Elements on the target system- If there is a match, that means that the Element from the source system was already migrated to the target system once in the past, and it needs to be updated. The Utility will proceed to the next step
- If there’s none, it means the new Element has to be created. The Utility will proceed to the next step
 
- The Utility checks all existing Elements on the target system to see if there is a match by name,typeorsegment_id- If there’s no match, the Utility updates the Element or creates a new one
- If there is a match in all three parameters, the Element from the source system won’t be migrated and the error message will occur
 
 The Migration Utility also ensures the uniqueness of Portal Pages. It checks name,internal_name, andURLof every Portal Page existing on the target system. If all three match, the Portal Page from the source system won’t be migrated and the error message appears.
