​@bingy I am trying to do something similar. Did you make any progress on this?

There is no out of the box solution but by using the HTTPCaller and Enterprise Rest API it can be done.

Here’s working examples and blogs for Data Interoperability that can be applied using FME Form as well.

The first one is my favorite when writing attachments to a geodatabase.

Here’s an ESRI Community question that talks about attachment too.

https://community.esri.com/t5/arcgis-data-interoperability-ques/write-attachments-to-agol-feature-service/m-p/1549037#M294

My comment below this community question shows some guidelines in writing attachments across the ESRI stack and a response to the person who asked the question that we resolved his Enterprise solution together.

Hi salvaleonrp,

We are looking to do something similar at work, but have not figured out how. This looks very promising. Is it possible to get a hold of the script to dwelve into it a bit more? :-)

Best regards,

​@hi_dog please pm me your email.  Thanks!

I wonder why this article did not appear on the Related Topics.

Anyway here’s a more direct solution avoiding the HTTPCaller.

Hi, could I please get a copy of the fmw if possible? Thanks

​@toshfly please DM you email to me. Thanks!

​@salvaleonrp 

Could you please share me the workspace 

abnan0001@gmail.com

i shall be thankful to you 

I sent you the file the last time you asked for it. However, the solution has dramatically improved with the ArcGISAttachmentConnector hub transformer.

Please read this article as intro to use as template for your solution … https://support.safe.com/hc/en-us/articles/37177466948877-How-to-Use-the-ArcGISAttachmentConnector

Thanks for the response and I have already implemented with this approach from service to local machine download for attachment and then uploading back to new feature service file..

My Query is 

From Feature service(ArcGIS Onlineconnector and ArcGIS Attachment connector) to Designed new master GDB with attachments to be stored.

Any Approach on this 

My comment on the article , I have asked last 10days before.
Thanks​​​​​​​

I did not see your comment on that article, besides you used another profile name. I responded to your question on this post. If your destination is to a geodatabase then there’s a well written document and video that’s been available for a while.
