Many times I move apps between environments, I update the web map id (config.json => itemid), and find-replace all rest url's (notepad++ is great for that).
Now I've used external data source in the app. These sources are from the same web map used in the app. I use them in InfoGraphic widgets#.
The migrated app shows "No data" for all these widgets.
What should I change in order to reconnect to the external data source?
I do not have dev edition in the production environment...
I'll appreciate any help.
