If I am working with older data, either my own or something I've downloaded, I get the warning "This item has authored FGDC metadata that must be upgraded to ArcGIS metadata format before it can be used in ArcGIS Pro." Since there is no way to update the metadata within Pro, I have to pass it through ArcCatalog to "Update Metadata" before going back to Pro. It would be nice if I could update Metadata directly in Pro.
