Can Geospatial PDF Reader Transformer read pdf maps as pdf maps (no spatial feature or table) from SharePoint and publish it as PDF on ArcGISOnline?

Yes this is technically possible.

• Use SharePointOnlineConnector's to connect to SharePoint and list and download the pdf files.
• Use ArcGISOnlineConnector's to upload the the files and share the uploaded items.

The hardest part is to get the SharePointOnlineConnector and the ArcGISOnlineConnector to work, but this is more a permissions / IT challenge than a technical one.

Thank you so much for your input. Much appreciated! My ArcGIS Online Connector is working, I am figuring out SharePoint Connector. Thank you!
