Upgrading from Raspberry to Beelink S12

Hello,
following the guide for using an Existing Data Drive.

I flashed StartOS to the new Beelink S12, then I selected “Recover” and “Use Existing Drive” at startup. the external drive is connected via USB.

This is the error I got.

What am I doing wrong?
Thanks

You are changing platforms and will need to use the Transfer flow instead.
