400: Bad Request on self-service flows​

Make sure you are starting and finishing the request in one browser. Self-service browser flows need to be executed in the same browser from start to finish!
Starting the flow in Safari and completing it in Chrome won't work. API Clients like Electron, Postman or Insomnia are browsers themselves, which can cause requests to fail. For testing purposes cURL is a good choice.

How can I separate customers/employee data, but have them use the same login dialog​

We want to separate our customers and employees, so we store them in different databases. But we would like to have them use the same login dialog for our portal.

You can deploy Ory Kratos two times, and use the same login UI pointing to two different Kratos login endpoints - /login/customer or /login/employee, either by having two different login routes, or by adding some logic to your login UI that reroutes customers to /login/customer and employees to /login/employee. So you define the same login or registration UI URLs in both of the Kratos configurations. You may need to tell your login/registration UI which Kratos it's supposed to talk to. The instances are cheap to deploy and the databases are isolated from each other. For example something like /login/customer and /login/employee.

How can I verify in advance if a username is available during registration?​

You can't right now. It would allow account enumeration attacks. See also the section in the documentation.

Do have plans to support automatic user migration scenarios?​

For example configure a callback to the legacy system when you can't find the corresponding user, and store the identity on successful legacy system response.

An alternative to callback and custom code is fronting the legacy system with Ory OAuth2 & OpenID Connect (Ory Hydra) and then using that as an upstream in Ory Identities (Ory Kratos).
