Hi, I have found an easier way. Put the datasource in 'report' folder, NOT in 'data source' folder. In Folder 1, before export, point the datasource to desired new databaseFrom Folder 1, export. In Folder 2, import.You will find that all reports in Folder 2 now pointing to the new databaseChange the datasource in Folder 1, pointing back to its original database Hope you can try and give me feedback. (Basically I created this steps based on Hazawa's hint)
