Hi Adam, So that means I have to export first my resources from version 3. If I get it right, I must first create a JSON file that configures all resource export mappings? I'm looking at this document, and I hope I'm looking at the right locaton. http://arches-hip.readthedocs.io/en/latest/system-administration/#exporting-data
I want to first do a test export and import for a particular heritage area (I'm looking into Silay City). If I'm satisfied with the results I will export and import for the rest of the resources from version 3. Any inputs from others?
