Casa App is designed to make it easy to transition your multisig setup to a new mobile phone.
If possible, retain your old phone until Casa App is all set up on your new phone.
Prior to following any of the steps here, perform a Health Check on your Casa App's Mobile Key to ensure that the key is backed up properly to the cloud and ready to be restored on your new phone.

How do I restore my multisig setup on my new iPhone?
If you had your Mobile Key backed up on an iPhone previously, then your new phone needs to be an iPhone. (If you are switching to iPhone from Android, please see Switching between iPhone and Android for instructions.)
- Log into your Apple account in the system settings of your new iPhone
- Log into Casa App
When you log into the app, you'll notice that all of your hardware keys and the Casa Recovery Key show the same configuration as they did on your old phone. That's because these keys are unaffected by the transition to your new phone.
If you are missing your Mobile Key, go to the Mobile Key screen and select “Restore Backup from iCloud."
Casa App will then pull the encrypted backup from Apple's servers and restore the key in the app for you.
What if I didn't have a backup of the Mobile Key?
If you didn't have a backup of the Mobile Key, but you still have access to your old phone, you can log into Casa App on that old phone and create a backup.
If you didn't have a backup of the Mobile Key and you don't have access to your old phone, don't fret! You can still make a recovery transaction to a new keyset using your remaining keys.
