Note

On (new) Key Gen 2 the restore are NOT done on the first system settings page (/settings/system).

Restore are on another page: /settings/updates > Click Network > Open

This button will open the settings page for the network on the new Key Gen 2, and from here (/network/default/settings/system) the Restore > Restore Backup > Import button will actually work, and the Gen 1 Key .unf file can be imported and used for restore.

Steps to migrate from Unifi Cloud Key Gen 1 to Gen 2:

1. Startup new key on your network, and do basic initalization (I used mobile app, make sure your mobile phone are not connected to a Wifi, and enable Bluetooth)
2. Keep both Keys on network
3. Login to new Key and old Key using a computer
4. Upgrade the all possible options for software and firmware on both new Key and old Key to latest version
5. Using computer: On old Key, go to Settings > Sites. Scroll all the way to the bottom, and click the grey button Export sites. Follow the instructions, i will type them down here:
6. Your old config .unf file will be downloaded to your computer
7. Restore that file into your new Key (/network/default/settings/system)
8. Migrate all devices
9. Wait 5 minutes
10. Forget all devices on your old Key
11. Shut down your old key from Settings
12. Done. For convinience: Adjust the IP of your new Key to match the IP of your old Key

2nd possible solution

1) Download a backup of your current controller.
2) Shutdown the old controller.
3) Plug the new UCK in.
4) Configure the UCK UI
5) Set a static IP ( same as old controller )
6) Import the backup.
