When using the `getpaymentacctform` method from bisq cli, I saw the following text:

```
"_COMMENTS_": [
    "Do not manually edit the paymentMethodId field.",
    "Edit the salt field only if you are recreating a payment account on a new installation and wish to preserve the account age."
  ]
```

So I understand that it is possible to restore my payment accounts from my persona GUI instance in the daemon by filling in the form properly.

I also asked about this topic in bisq's matrix chat and I got told that the structure of the data in bisq-gui and bisq-daemon should be the hence, and that means that copying the `UserPayload` file could do the trick. 

Update: yes, the above trick works. I checked myself in a test environment.
