Customers who have legacy user databases they wish to import can use this feature as part of initial or ongoing migration to Phase Two. We use a variant of this Keycloak user migration extension.
In order to migrate your users with this extension, you must implement a web service so that we can securely validate the users and receive their information. The API to be implemented is documented in the next section User Migration API. There is an example implementation in Java on Github legacy-system-example.
You can add a legacy migration in the User federation section of the Admin UI. Select the User migration using a REST client provider and configure your endpoints.
