Can ArcGIS Desktop mxds be read into ArcGIS Professional with all settings maintained and then saved in the ArcGIS Pro format?
If not, is there a conversion tool that will allow the settings of mxds to be maintained if the work in the mxd is then moved to ArcGIS Professional so all the work to create the mxd is not lost, especially if the mxd was quite complex and very time consuming to duplicate?
