How to Restore Signal Chat to a new phone
If you switch to a new phone, you can move the backup from your to a new phone and then use it to restore. Since the backup can be moved to the cloud (manually), you can download it to a new phone and then manually choose to restore it. However, make sure to save it into the internal storage of the phone. The rest of the process remains the same. Backup and Restore methods in the Signal app are secure and protected with a passphrase. It is difficult for anyone to read and restore it to their phone. Also, the backup seems to be a manual process instead of an automatic one. So make sure to do it from time to time.
