Is it possible to transfer data from Portal for ArcGIS to ArcGIS Online?

Answer

Yes, it is possible to transfer data from Portal for ArcGIS to ArcGIS Online. Data can be transferred either by republishing web maps and services to ArcGIS Online or by using ArcGIS Online Assistant.

If there is a large amount of data, republishing web maps and services can be time consuming. However, ArcGIS Online Assistant shortens this process by providing drag-and-drop functionality.
