There are two options to import/export Assets and Inventory Plugin data: Excel (CSV) and JSON
The main difference with Excel and JSON formats is Excel imports work incrementally where JSON works like JIRA xml export (means restores all data). Many users find Excel import is easier than JSON to implement.
Import/Export via Excel (CSV)
You can export your Assets and Inventory Plugin data to Excel file as well as import from Excel.
Import/Export via JSON
You can export your Assets and Inventory Plugin entire data to JSON file as well as import from JSON. This a complete backup and restore process.
Destructive operation!
JSON Data import will wipe all existing Assets And Inventory Plugin content, including the Asset custom fields' value for the JIRA issues. It is strongly recommended that you backup your database first!
