Help requested for sharing field map attachments to a feature layer in ArcGIS Pro

[FionaNicholls]

I have points with photo attachments as a feature layer created using field maps app.  The feature layer is shown on a web map. 
I have imported that web map with the feature layer into ArcGIS Pro.

In ArcGIS Pro I have another point layer, feature class, created from surveyed points with coordinates and calculated building floor levels.  These point layers have a common field being the address. 

I would like to add/join the field map feature layer attachments to the feature class points in my gdb and share that one feature class with the client. 

In ArcPro, I have tried exporting the feature layer to a feature class but the attachments to not export.

Has anyone had success with this?  Is there an alternative way to share the photos with the client where they match the feature class points.

If you’re wanting to simply create a feature class for your client, create a file geodatabase, join your two sets of data (based upon the unique field you mentioned) and then export this joined data to your FGDB. This will bring the attachments into the newly created feature class.

If you’re looking to keep the data in the original/existing feature class and you’re wanting to add the attachments created in Field Maps to it and then share this with your client, use the add attachments tool. Keep in mind, for this feature class, attachments must first be enabled.

Hope that helps.

Thank you Eugene, the first part worked well. I am happy that I have a feature class in the gdb I will share with our client and the attachments are there even though I now have a duplicate point. 
I was also directed to the support page for assistance with copying attachments from one feature layer to another and it is quite complex. How To: Copy Attachments from One Feature Layer to Another in ArcGIS Pro
