I need to push out an app-update, that sets the app (app-A) up for being migrated and retired. The new app that users will migrate to (app-B, different bundleId) is ready, so I would prefer it, if there are no new users to app-A.
Concretely: Can I offer app-updates to app-A, while preventing users from installing it new?
I have seen this not-encouraging post from 2017: iOS App Store - retiring an app - Can I hide the app from new users while making updates available to all existing users - it's been a while, so things are looking better presently.
Creativity is allright here, but obviously any updates to app-A needs to pass review, so it can't just be an empty shell that points to app-B.
