Explanation
Granting authors access to the FAQ record type is the recommended solution to correct the problem of authors being unable to create FAQ article types after migration from Knowledge to Lightning Knowledge. A record type is a way of defining different business processes, page layouts, and picklist values for different types of records within an object. A record type can be used to control which users can create, view, edit, or delete records of that type. When migrating from Knowledge to Lightning Knowledge, each Classic article type becomes a Lightning record type. Therefore, granting authors access to the FAQ record type can enable them to create FAQ articles in Lightning Knowledge.
