When using ArcPy to update the data source URL for a map containing the utility network feature service layers, only the utility network layer is updated.
This works in ArcGIS Pro 3.2. Refer to the following example:```aprx = arcpy.mp.ArcGISProject('current')m = aprx.listMaps('sqlsvr')[0]m.updateConnectionProperties("https://utilitynetwork.esri.com/server/rest/services/RedTrolley31_SQLServer/FeatureServer", "https://utilitynetwork.esri.com/server/rest/services/RedTrolley31_Oracle/FeatureServer")```
