I have a map service that include Mosaic Dataset (Map service and NOT image service)
I am trying to use arcpy to update from one server to another.
I try to use layer.updateConnectionProperties but it does not work.
The closest I get is layer.updateConnectionProperties(None, ’https://newserver/arcgis/rest/map1/MapServer’, validation=False)
It gave me layer that have the correct source but is show with red exclamation mark and does not display.
The mosaic is really a group of 4 layers but only the group can be changed.
I noticed that is I try to open the properties in Pro and go to source the “set source” button is disabled.
Is it possible?
