Update sourceUrl for a feature service?

Question

For referenced feature layers brought into AGO from our enterprise server I can access the sourceUrl using item.sourceUrl. Is it possible to also update the sourceUrl?

I'd like to point the referenced feature layer at a different REST URL to update the underlying data without creating a new item and losing popup configuration, etc.

I am getting the same errow when attempting to update a service in ArcGIS Online that has been brought over from Portal. We have a new Portal and I wanted to swap in a new url and credentials. The update() returns true but it does not persist. I get the same exception above.

Just want to confirm I've encountered the same issue. I've tried using ArcGIS Online itself, AGO Assistant, Geo Jobe and the ArcGIS API for Python. All methods appear to save the changes, but the changes don't persist and the source URL remains the same.

There appears to be no way to update the source URL for in a referenced feature layer.

Thanks for the ideas @JakeSkinner and @EarlMedina!

I've tried both these methods and haven't been able to get either to work. My first thought had also been to use AGO assistant, but I'm trying to change the source URL for an item, not in a layer in a web map. When I go to the item details in AGO assistant, I can edit the JSON and change the source URL but the changes don't actually stick when I save them.

The code suggested here throws an error I've run into before trying to figure this out:
