i have two hosted feature layer with the same field.
I would like do like a merge in Arcmap.
It's possible in AGOL?
I have allow attachments to.
In AGOL there is the Merge layer tool (see: Perform analysis—ArcGIS Online Help | ArcGIS ) but I am not sure how and if it will handle attachments. Sometimes it is easier (in case it is a one time action) to download the data and merge it locally.
