Batch Update Data Source in Pro Map - python/CIM

I recall unsuccessfully traversing this topic a couple months ago (did not post here though). Simple question. I have multiple layers in an ArcGIS Pro map. I have created an updated feature class WITHIN the same gdb, but with a different name. Currently I have 15 layers utilizing the same data source path/to/zachs.gdb/fc_name to path/to/zachs.gdb/fc_name_v2. note that the 15 layers have definition queries for 15 different value. I have found the documentation on how to use the cim to change the dataset or gdb underlying the source, but NOT if there is simply a different FC in the same path/to/gdb/<dataset>.

BELOW code adapted from here (https://pro.arcgis.com/en/pro-app/latest/arcpy/mapping/updatingandfixingdatasources.htm) BUT there are no methods or properties in the CIM or elsewhere to update my FCs if it's just a name change. Ideas? Can be with CIM or any module...

p = arcpy.mp.ArcGISProject('current') m = p.listMaps('zachs_map')[0] l = m.listLayers('group_w_15_layers')[0] layer1 = l.listLayers()[1] layer1_cim = human.getDefinition('V2') dc = layer1_cim.featureTable.dataConnection dc.workspaceConnectionString

thanks!

Looks like update connection properties will do that for you.

I'd start with the first example under "Using the connectionProperties dictionary".

You are 100% correct. I always confuse database and dataSET. Took me some fumbline, but eventually...Thanks @RhettZufelt !

# Update the Feature Classe(FC) source in TOC via the CIM # In this example, multiple Layers nested in Group Layer, all same source, # with Def Queries to make different. import copy p = arcpy.mp.ArcGISProject('current') m = p.listMaps('map_name')[0] # Get Layer Group from TOC containing the species layer spp_group = m.listLayers('spp')[0] # Now get list of all layers spp_lyrs = spp_group.listLayers() # loop through and update layer source FC to species_v2 for spp in spp_lyrs: cp = spp.connectionProperties cp['dataset']='species_v2' spp.updateConnectionProperties(spp.connectionProperties, cp)
