Now that the legacy Firebase APIs are being deprecated, it appears this might include the Instance ID Server APIs.

We are currently using the Instance ID Server APIs ‘batchImport’ method to convert APNS tokens to FCM device registration tokens on the back-end.

Is it using the Firebase Admin SDK to do the same thing? To convert an APNS token to an FCM device registration token? Or is it even necessary anymore to be able to send a push-notification to an iOS device using the Admin SDK? Can we use the APNS token directly?

Thanks —
