Converts all ArcMap documents (.mxd) in the script's folder into ArcGIS Pro Projects - requires amaptor (available via pip and at https://github.com/ucd-cws/amaptor). Has infrastructure to convert everything in a folder into the same project, but would need some retooling for it. Must be run from an ArcGIS Pro python environmental w/amaptor inst…
