How do I restore my backup on a new phone?

Install WitnessWork on the new phone and bring your account over. With your old phone, use Set Up Another Device: during setup, tap "I already use WitnessWork", then From your other phone, and scan the code on the old phone (Settings → Account → Set Up Another Device). Without your old phone, use your recovery key: Settings → Account → Use a Recovery Key. The new phone then offers to restore your backup. When your other devices use Cloud Sync and are at least as up to date as the backup, your records arrive through Cloud Sync instead. If it has no records yet, tap Restore. If it already has records, choose Combine to keep them and add the backup's, or Replace to use only the backup. Restoring combines every device's backup on your account. You can also restore later from Settings → Account → Restore from Backup. A backup from a newer version of WitnessWork is left out until you update, and one that can't be read is skipped; the app tells you. When iCloud Keychain or Google's backup brings your account back on a reinstalled phone, the app offers your backup once. Afterwards, turn on Backup on the new phone too.
