How can I apply tested changes to a deployed app?
If I have a client app that I want to make changes to,
I prefer to copy the app and make changes and test in the copy before rolling out to client.
Is there a way to merge my finalized changes into the client app from my test app without having to manually apply the changes to the client app?
Re-applying changes manually can be error prone.
Alternatively, can the deployed app be replaced in some manner so proper App ID is retained?
I can think of un-deploying, deleting, copy test app and deploy copied app, etc…but that seems messy!
