Scotland drew 0-0 away to Ukraine in the Nations League on Tuesday, securing a crucial point that sealed their promotion to the competition's top tier as the war-torn country hosted their final group game in Poland.
Scotland, who started the inaugural edition of the competition in League C, finished top of League B-Group 1 on 13 points – two ahead of Ukraine.
They had needed to avoid defeat to guarantee their second promotion in three campaigns.
While both teams had chances, the best opportunities fell to Ukraine, with Andriy Yarmolenko firing over the bar from close-range in the eighth minute and Mykhailo Mudryk's effort saved by keeper Craig Gordon just after the break.
Steve Clarke's Scotland, who lost a World Cup qualification playoff 3-1 to Ukraine earlier this year, have won four and drawn one of their last six games.
CZECH REPUBLIC RELEGATED AFTER SWISS LOSS
Two goals in a minute from Remo Freuler and Breel Embolo steered Switzerland to a 2-1 victory over luckless Czech Republic at Kybunpark, a result that relegates the Czechs from Nations League A.
World Cup-bound Switzerland finished third in Group 2 with nine points from their six games, two behind winners Spain, while Czech Republic could only manage four points in the campaign.
Freuler headed Xherdan Shaqiri's cross into the net on 29 minutes and straight from the kickoff Embolo collected a loose pass, ran to the edge of the box and fired a low shot into the bottom corner.
The visitors reduced the deficit before halftime when Patrik Schick scored with a left-footed finish from David Zima's low cross, while later Tomas Soucek saw his penalty saved by Swiss goalkeeper Yann Sommer on a tough night for the visitors, who also struck the frame of the goal on two occasions.
