Rangers will face Salzburg or Twente in the Champions League play-off if they overcome Dynamo Kyiv.
Hearts will take on Kryvbas Kryvyi Rih or Viktoria Plzen in the Europa League play-off.
And in the Conference League play-off, Kilmarnock will face Copenhagen or Banik Ostrava should they beat Tromso, while St Mirren will meet Corvinul Hunedoara or Astana if they defeat Brann.
Dynamo and Rangers meet for the first leg of their third qualifying tie on Tuesday in Lublin, Poland, where the Kyiv side are playing due to the Ukraine war. The return game will be at Hampden, with Ibrox currently unavailable amid renovation work.
Austrian Bundesliga runners-up Salzburg host Dutch outfit Twente, who were third in last season’s Eredivisie, in Tuesday’s first leg, with their return match also next Tuesday.
Rangers, who would be the home team for the first leg on 21 or 22 August, recently sold Sam Lammers to Twente and bought Robin Propper from the same club. The second leg would take place the following midweek.
The draw for the revamped Champions League proper, which will feature Scottish Premiership winners Celtic, takes place on 29 August, with the first of eight rounds of fixtures in mid-September.
Hearts will be away from home first on 22 August against Ukraine’s Kryvbas Kryvyi Rih, who are playing their home ties in Slovakia, or Czech side Viktoria Plzen. The return leg at Tynecastle will be seven days later.
Like the Edinburgh side, both of the potential opponents finished third in their domestic league last term and Plzen were runners-up in the Czech Cup. They play each other over the next two Thursdays, with the second leg in Plzen.
A win takes Hearts through to the league phase, lose and they will enter the Conference League group stage.
