Big fan of the data source replacement option in Dashboard, and it actually saved me a lot of time on a project this week when moving from Dev to Production. While it's great, I spend 99% of my time in Experience Builder and find myself spending many hours manually swapping layers and reconfiguring them in Experience Builder as we change data sources and overhaul our data.
"Why don't you just swizzle?" you may ask. Well that IS a great option, except in AGOL or when the schema changes for a dataset. In AGOL, I can't access the config file directly on the server like I can in Enterprise, and editing the config in Esri Assistant breaks more things than it fixes. No matter what, I'm out of luck with schema changes. Having an option for data source replacement in Experience Builder would easily save me hundreds of hours every year!
