Solid Stuff Doug , I use VertiGIS Item Manager very often to do exactly what you showed in the video, change the references to our 40 plus sub layers as we have a dev/preprod/prod environment and I made that mistake before changing the urls without the item ID. I will pass this video along to others as well to learn this very useful method. As a note, Item Manager is free to use to anyone with an AGOL/Enterprise organization once you register.
