The league will now consist of Divisions 1A and 1B (with ten teams each) and 2A and 2B (with sixteen teams each).

• Play-off between bottom club in Division 1B and 5th team in Division 2
• Top four clubs in Division 3 promoted to new Division 2A
• Play-off between bottom club in Division 2 and 5th team in Division 3

Professional players will be banned from participating in Division 2 matches and foreign professional players from playing in the League at all. Division 1 sides will only be able to field two professional players in their matchday sides and only one may be a forward. The new structure will remain in place until at least 2017.
