Transfer documents to your new device
There are several ways to transfer scans between devices.
Automatic transfer with Genius Cloud
If you do not have Genius Cloud yet, you can sign up to Genius Ultra on your old device and follow the next steps.
On your old device, tap the Backup & sync button above the document list to ensure that all your documents are uploaded to Genius Cloud.
On your new device, tap the Backup & sync button above the document list and log into your Genius Cloud account.
Your documents will be downloaded from Genius Cloud to your new device.
Restore an iCloud/iTunes backup
Ensure you have an iCloud or iTunes backup of your old device, and you will be able to restore it on your new device. This Apple tutorial explains in details how to proceed.
Make sure to select "Restore an iCloud Backup" when you set up your device. If you select "Set up as a New iPhone" in the Apps & Data menu (step 5 of this tutorial), you will not be able to recover your Genius Scan data even if you later log into your iCloud account.
Restore a manual backup
You can create a backup of your Genius Scan data on your old device, and restore it on your new device.
