The current App Upgrade uses the metadata of the specified app and overwrites everything.
My request is to be able to select which metadata to apply.
For example, since the app specified in Copy app is usually given the name of the development environment, this can be used to exclude the reflection of that app name.
Also, although I haven’t imagined it yet, if you can specify the data source, you may be able to operate different databases in production and development environments.
When this feature is implemented, it would be better if the upgrade can be executed in two steps, Validate and Deploy, to prevent unintended upgrades from being applied.
I understand that this is a difficult request, but I think it would expand the AppSheet development methodology.
