Hi @yagizhan14 , would you mind providing a link to your specific app? We’re close to enabling some app developers to move their app to forge without losing customers, but not quite there yet - still in alpha. There are still some missing features that mean it’s not suitable for every app, and we haven’t yet finished the work to enable converting your listing and installations.
It should soon be possible to at least test migrations from connect to forge on a test site, however. We’re announcing the changes as they come out in this thread
