I am trying to archive my old maps and hosted feature layers saved online by saving them as project packages in my local harddisk. After doing so, I delete the files online. However, when I try to re-open the project package, I get the error that the data link is broken because I think it is looking for the data source online.
A workaround would be to export each layer in Arcgis Online and download each one before deleting them, and then upload them back before re-opening the project, but that is very tedious if there are a lot of layers.
Isn't there a way in Arcgis Pro to also save the underlying tables (not only the reference) when creating a project package or a layer package?
