I have a codebase that won't publish to a sandbox since uses an app ID from another app I deployed to AppSource. Is there a way to generate a new app ID for this codebase (it isn't deployed to AppSource)?

No, you will have to withdraw your original app and publish the app with a changed AppId as a new app.

Is the only way to change the app ID through a creation of another project using AL:Go? And just copying the code/logic of the extension on the newly created one?

The App Id is a Guid. You can generate a Guid and use that as the App Id. The VS Code Extension "Create Guid" by mwallace is good for this type of generation.

Will changing the app ID of an app cause any problems?

I recommend you create a new copy of your code with the new AppId.

Either through a branch on git if you use that or by simply copying your VS Code project to a new folder.

Do not just change in the app you already have published in case you need to maintain something in the already published version.

Yes, you can unpublish it from the MS Partner senter.

It depends on the state of the app and environment, but in short - If you're working with PTEs, changing the App Id will change the underlying table and table extension references to the new GUID, which will appear to be data loss (you can create something to copy the data if needed).

AppSource App offers are tied to the GUID.

Hi, changing the Guid will create a new table in the database, which means that your original data will be completely lost.

I have mentioned in the link below how to change the Guid.
