At the same time, in 1963 the Class B tournament was shifted one tier down in the Soviet league system.
The structure of the tournament was preserved having separate competitions for Russia, Ukraine, and other Soviet republics.
The pair of the first placed clubs was sort of a republican championship playoff.
Note teams were relegated or withdrawn and only one was promoted to the Subgroup A (the First League).
They were classified as the Republican champions and were promoted to the Inter-Republican level, the Class A.
