If you want to change your Flamelink project from the Realtime Database (RTDB) to Cloud Firestore (CF) or from Cloud Firestore to the Realtime Database you can do this in a few steps.
Please note that your content will not automatically be transferred to the newly selected Database.
For now, migration of data from the old to the newly selected database will need to be done manually.
1. Select "Manage Project" from the project menu on your Projects Dashboard
2. Toggle between Cloud Firestore and Realtime Database
3. Select "Update" & Confirm the updates.
4. Once this has been done, you can navigate back to your Dashboard
5. Note: You will need to log into your project again.
