Inter Allies took the final step to the elite ranks, confirming their place in next season's Premier League after gaining promotion on Monday.
Inter Allies needed a single point from their last Division One promotion league to end their long wait for qualification for their debut in the flight football.
But the Accra-based side defeated Danbort FC 2-0 in the final play-off contest at the Len Clay Stadium to record their third straight victory in the three-game series.
Illiasu Fuseini and Patrick Bortey scored both goals for Inter Allies.
In the other promotion game, Nania FC pulled their first win, defeating Okwawu United 2-0 at the Baba Yara Stadium.
