I have a layer on ArcGIS Online that has tons of features, all with photos attached. We recently decided to split this layer up into smaller layers (i.e., one for each project). So I downloaded the layer as a file geodatabase, in order to preserve our domains and download the photos. The photos are indeed there when downloaded. Then I try to re-upload them to ArcGIS Online, and the photos disappear. So how do I upload a feature class to ArcGIS Online and preserve the attachments?
Also - is there a better way to split up a large layer into smaller layers without downloading and re-uploading? I've already tried this copy layer and save layer thing, but it just creates many layers that point back to the same data, which is not what I'm looking for.
Thanks!
