In the summer of 2012, the Swiss Football Association restructured their league system.
This reconstruction was done to decrease the competitive gap between the two top tiers by converting the second to a purely professional league.
The new Promotion League would therefore serve as the semi-professional link to amateur football.

Liga were Fribourg, Yverdon-Sport, Old Boys, Breitenrain, Tuggen, Schaffhausen and YF Juventus.
