^Iraklis withdrew from the league because of Financial Problems. The founding club (Athlitiki Enosis Pontion Katerini) stopped to exist too. The original Gymnastikos Syllogos Iraklis would decide if a new football team will start from the Third Category of the local championship Macedonia Football Clubs Association, or if the football team of G.S. Iraklis will be merged with 1st category (A1) Macedonia Football Clubs Association club Iraklis Ampelokipi, as it happened before 5 years with Athlitiki Enosis Pontion Katerinis F.C.. The club was therefore automatically disqualified from the tournament.
Each tie in the knockout phase, apart from the final, was played over two legs, with each team playing one leg at home. The team that scored more goals on aggregate over the two legs advanced to the next round. If the aggregate score was level, the away goals rule was applied, i.e. the team that scored more goals away from home over the two legs advanced. If away goals were also equal, then extra time was played. The away goals rule was again applied after extra time, i.e. if there were goals scored during extra time and the aggregate score was still level, the visiting team advanced by virtue of more away goals scored. If no goals were scored during extra time, the winners were decided by a penalty shoot-out. In the final, which were played as a single match, if the score was level at the end of normal time, extra time was played, followed by a penalty shoot-out if the score was still level. The mechanism of the draws for each round is as follows:
In the draw for the round of 16, the eight group winners are seeded, and the eight group runners-up are unseeded. The seeded teams are drawn against the unseeded teams, with the seeded teams hosting the second leg.
In the draws for the quarter-finals onwards, there are no seedings, and teams from the same group can be drawn against each other.
