I have a map I am making where all I want to do is change the source layer for a raster to a new layer. I would then like to apply the same symbology as the original layer, but change the min and max values used to stretch the raster.

So far I have done this:

import arcpy

#load in aprx
aprx = arcpy.mp.ArcGISProject("in_aprx")

#get the maps
one = aprx.listMaps()[0]

#update the current raster with a new raster, this new raster has different min and max values which is what I ultimately want to change

one.updateConnectionProperties(original_layer, new_layer)

#save a copy 
aprx.saveACopy("new_map.aprx")

I can access the layers symbology like so:

one_layers = one.listLayers()

one_layers[0].symbology

but I am not sure how to change the min and max values from here. As of now the minimum and maximum are being used from original_layer which are very different and results in poor stretching.
