Amini and Aarhus advance 3-1 on aggregate after a goal-less first leg.
They now have the chance to secure their Superliga future with victory over Viborg.
Mabil and Esbjerg will meet Horsens to avoid automatic relegation to the Danish second tier.
The Superliga has introduced a new competition structure this season, including a convoluted relegation process.
The bottom four clubs have been split into two play-offs.
The winners of Esbjerg versus AGF and Viborg versus Horsens (now confirmed as AGF and Viborg) will meet each other in the next round, with the winner of that two-legged tie avoiding relegation.
The losers (Esbjerg amd Horsens) will also meet, with the loser of that two-legged play-off to drop down into the second tier.
The remaining two clubs - effectively 12th and 13th in the 14-team league - will play second and third from the 1st Division in promotion-relegation play-offs
