We have an ArcGIS Online hosted feature service that has ArcGIS attachments. Using FME, I have no problem downloading the feature service to a feature class in an ESRI file geodatabase, including the attachments. Now our users edited the downloaded feature class, I will need to upload the feature class to ArcGIS Online to overwrite the content of the previous hosted data. Overwriting the feature data works fine, but I can't find a way to bring along the attachments. I am trying to do a truncate/insert operation. Any idea how to do this correctly?
