Transfer photo attachments to overlapping points in another feature class

[AaronKoelker]

Long story short, I have a need to transfer photo attachments from one feature class to another based only on an overlap/intersection. I'm having trouble thinking of a workflow for this (or perhaps I'm overthinking it). I do not have any reliable attributes like a GLOBALID to join between the two feature classes and transfer that way, I just have the matching locations. Fortunately the points I need to transfer attachments for overlap the points with the attachments exactly.

Any ideas? I'm open to either something I can script with python or do manually through ArcGIS Pro if necessary.  I do have thousands of points, however, so manually saving the photos one by one and reattaching them to their new points is something I'd rather avoid.

Thanks, currently I'm trying to attempt something close to this workflow: https://support.esri.com/en/technical-article/000014520 and using a spatial join in the place of Step 4. It also uses the workflow you linked as one of the steps. I'll come back and update if it works.
