To Clarify: We have three stacks, Development, Staging, Production.
EACH have their OWN separate: SQL Database, ArcGIS Server, IIS with Portal/Web Adaptor servers. (yes, I understand that's like 9 servers)
If I take the time to create AGS Services, Webmap and then a WebApp (dev edition) on my development stack. Do I really have to Re-create all of that with my staging server, then again on Production? The WebMap and App is pointing to the Dev Portal, not staging. I get warnings and errors when I try to move from one WAB Dev Edition to another. Esri Tech support is recommending a kind of "find-and-replace approach" for the code, Which, (no surprise) broke the app.
Can one deployment of WAB point to Two (or three) separate Portals and then I can just change the webmap between them?
Or is the idea of a Dev stack juts represent Practice for production and you have to redo it all anyway?
