What I'm specifically looking to do is update references to demographic layers I don't own in any/all content within my organization. For example, I would like to search for any users' story maps or web apps that are referencing the 2016 Tapestry Segmentation layer, and update those maps and apps to point to the 2017 Tapestry layer instead. I found some information about how to update my own hosted feature services by creating a service definition file and publishing/overwriting the existing in a Python script here, but I'm wondering if this can be done using layers from the Esri Living Atlas and other sources that I do not own or am not able to otherwise update the feature layer itself.
