I found this very helpful article https://support.esri.com/en-us/knowledge-base/how-to-transfer-attachments-between-feature-layers-of-... from 2023 but something goes wrong in the last step when adding the attachements.
First of all my ATTACH-table does not contain "REL_OBJECTID". I don't know why, does it has to do with versions of ArcGIS Pro when the feature class has been created? Instead there is "REL_GLOBALID"
This means that I had to transfer the GlobalID from the feature class containing the attachements to the feature class that the attachements are transfered to.
When running Add Attachements with "REL-GLOBALID" as Match Join Field I get that the tool succeeded but that it couldn't open a single file. Any ideas what can have gone wrong? I moved the folder containing the attachements from a shared folder to a local folder but no difference to the result.
The only thing I can think of is that the names of the attachements contains spaces and Swedish letters like åäö.
Any ideas are helpful!
