Hi Ercan,
You can. In fact, you can create the same app in both projects using the same package name/bundle id.
What you cannot do is reuse the sha-1 key across multiple projects. So if you've set up a SHA-1 for use with Play or Firebase Auth, then you need to delete the app before moving it.
Note that when moving SHA-1 keys you should always delete the app and associated SHA-1 from the old project and confirm it is working in the new project before deleting the old project. If you do not, then you may have to wait up to 30 days for the project to be purged from Google Cloud servers before the SHA-1 key will be available again.
