Convert Smart-Preview-Pano into full resolution version

I created a panorama from three photos while not connected with my file server, so the pano was created as "Smart-Preview_Pano.dng" file. Now after reconnecting to my file server I have access to the full resolution files and I would like to convert my smart-preview-pano (which obviously is lo-res) into a full-res version using my original files. Is there a way to do this, keeping all my settings & edits I made when creating the original smart-preview-pano?
