The 24 ties will be played on 14 and 15 August, after two preliminary-round ties on 31 July and 1 August.
The preliminary round features the third and fourth-placed sides in the Scottish Highland and Lowland Leagues, who will compete to join the winners and runners-up from those leagues in the first round, along with Championship, League One and Two sides.
English sides Sutton United and Boreham Wood will join six other non-Scottish sides in the second round. Crusaders and Coleraine will be the Northern Irish sides in round two, with Bohemians and Bray Wanderers representing Republic of Ireland and the New Saints and Connah's Quay Nomads the Welsh entrants.
Inverness beat Dumbarton in last season's final and Caley Thistle's meeting with the Pars is the only all-Championship tie in the first round.
