If you have a 1SE Pro subscription, refer to this article for steps to restore from 1SE Cloud. Otherwise, the steps below move 1SE to your new iPhone with an iCloud backup.
Step 1: Back Up Your Old iPhone Using iCloud
On your old iPhone, follow How to Back Up with iCloud and wait for the backup to finish—the date under Back Up Now should be from just now.
Important Note: Logging into iCloud on your new iPhone is not the same as restoring from an iCloud backup. 1SE is not stored in iCloud Drive; you must complete a full iCloud backup to transfer your data.
Step 2: Restore from an iCloud Backup
Turn on your new iPhone. If it's already set up, you’ll need to erase it first (Settings > General > Transfer or Reset iPhone > Erase All Content and Settings).
Follow the setup steps until you reach the Apps & Data screen.
Select Restore from iCloud Backup and sign in with your Apple ID.
Choose the most recent backup that includes 1SE and wait for the process to complete.
When the restore finishes, open 1SE and your projects are there. If 1SE opens empty, the backup didn't include 1SE—go back to Step 1 on the old iPhone.
For more details, follow Apple’s guide on restoring from iCloud backup.
We strongly recommend subscribing to the 1SE Pro plan to access the 1SE Cloud feature, making it much easier to move and restore your moments seamlessly in the future.
