Enable updating services rather than overwriting (ArcGIS Online/ArcGIS Server)

Idea created by jmarr on Sep 27, 2012
    At the moment, if you'd like to upload new data to an existing service, you must add it to the MXD and re-publish the whole lot. It would be great if ESRI could come up with a feature that checks which layers have changed in the service since last published, and provide an option to 'update' rather than the existing 'rewrite'.

    If one has a massive dataset that is updated every day, they won't need to upload all of it to the server each time - just add the new layers.
