We built several Experiences in our Development environment and need to promote them to our staging environment. After creating and importing the .epk file using, gorup content export, for the experience we need to remap the DataSources references to the corresponding, and already existing webmaps and feature services staging equivalents. I have tried using the ArcGIS assistant to update the resources/config/config.json file with no luck. Even a simple edit seems to corrupt the experience. I have also tried to update the items using the ArcGIS Python api. Is there any reliable/Best practice way to do this? Without having to basically rebuild the entire experience in the staging environment?
