Teams ranked second through fifth in each of the two groups will qualify for the promotion play-off, which will determine the last two promotion spots. The eight qualified teams will be drawn into two fixed brackets, each of which will contain the second and fourth place finishers from one group and the third and fifth place finishers from the other. All ties will consist of a single neutral-site match. In case of draws, an overtime period will be played; if the match is still tied following the overtime, the team which achieved a higher regular season finish will be proclaimed the winner.[3]
