Dealings created in New Landonline are fully compatible with Legacy Landonline. However, dealings created in Legacy Landonline will only be available in New Landonline if the instruments and functionality you want to work with are currently supported on the new application.
Content shown in this video may not represent the latest version of the New Landonline application, but this does not change the functionality or steps you need to take.
