Following a second-place result and a successful promotion playoff in 2003, Grossbardorf advanced to the Bayernliga (IV) where they played several seasons as a lower table side.

TSV's performance markedly improved and they finished their 2007–08 campaign in fourth place, which advanced the side out of the now fifth tier Oberliga to the Regionalliga Süd (IV) for the 2008–09 season.

Due to Regionalliga legislations on stadium size, TSV Großbardorf had to move to Willy-Sachs-Stadion in Schweinfurt for its home games.

In the play-offs the team lost 8–4 on aggregate to Regionalliga side SpVgg Bayern Hof, mainly because of a humiliating 1–6 home defeat in the first leg.
