Scottish Football League clubs have voted in favour of a proposed merger with the Scottish Premier League, reports BBC Sport.
The bodies will form a new Scottish Professional Football League in time for next season, averting a threatened breakaway from Division One clubs.
A revised financial distribution model will be introduced, feeding more money into the second tier.
The league structure will remain the same, with a top flight of 12 and three lower divisions of 10.
SPL clubs had already unanimously agreed on a package of measures that would deliver a merged league body for the new campaign and play-offs between the top league and the second tier.
There had been dissenting voices from Second and Third Division clubs but 23 of the 29 clubs voting backed the plan for restructuring.
A minimum of 22 votes was required, while Third Division champions Rangers did not get a say as they remain associate members having joined last summer.
