- On the old iPhone, check Backup. Open Vaultpod, Backup. It must say On with a recent time. Tap Back up now if not and wait for it to finish.
- Run Test restore. Same screen, type the recovery phrase. It must say the backup opens and every file is in iCloud.
- On the new iPhone, sign in to the same iCloud account and install Vaultpod.
- On the lock screen, tap Use recovery phrase, then Restore from iCloud. The backup downloads. Type the phrase and draw a new pattern for this phone.
- Repeat the phrase step for each vault you have. Each vault has its own phrase.
- Only now delete the app from the old iPhone.
Why a new pattern?
The pattern key is mixed with a secret that never leaves the old phone, on purpose, so a copy of the files cannot be attacked offline. The new phone has a new secret, so the vault needs a new pattern. The phrase works everywhere.
Shortcut: iCloud Keychain recovery
If you turned on “Recover with pattern via iCloud Keychain” in Backup, the new phone opens the vault with the pattern alone. The toggle explains the trade: anyone with your Apple ID and your pattern could then do the same.
