Change a feature layer Url

[MarkCederholm]

Is it possible to change the Url of a FeatureLayer?  For example, changing

"https://oldserver/arcgis/rest/services/myfolder/mymapservice/MapServer/1"

to

"https://newserver/arcgis/rest/services/myfolder/mymapservice/MapServer/1"

When I try this:

fLyr.manager.update_definition({ "url":sNewLayerUrl })‍

I get "RuntimeError: Invalid URL (Error Code: 400)".

hello Mark,

don't go so far, you don't need to go until the FeatureLayer object

Stay at the "Item" level, you just have to change the Item properties

item.update(item_properties={'url':newUrlString})

It works, thanks.
