I have setup a couple of geoprocessing services in Arcgis Server 10.1 that are based on python scripts. The geoprocessing services run just fine. However, there are times when I have to make small changes to the python scripts. Whenever that happens, I've been republishing the updated script as the geoprocessing service. I haven't found a way to simply "update" the geoprocessing service whenever there is a python script change. Restarting the service doesn't seem to incorporate the script changes. Is there any way to avoid republishing a python script as a service when a small script change occurs?
