Batch Update Data Source in Pro Map - python/CIM

Question

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".
