The 11th and 12th-placed teams of the Liga Națională faced the 2nd and 3rd-placed teams of the Divizia A, from both Seria A and Seria B. The first place from each play-off group promoted to Liga Națională.
Because the winner of Divizia A, Seria B, CSM Oradea declined the participation in the 2018–19 Liga Națională, another play-off match was organised to establish the third place and implicitly the last team promoted. The match was played between the 2nd places from the two Relegation play-offs series.
