Paul Dickov saw a summer of discontent and failed takeovers end with a convincing victory at Yeovil Town as they kicked off life back in League One.
Both teams were relegated from the Championship last season, Rovers suffering the drop after a last day loss at Leicester.
But Doncaster were quickly out of the blocks as they look to make an instant return to the Championship.
Debutant Curtis Main lofted a shot over home goalkeeper Chris Weale after only eight minutes.
Former Scunthorpe forward Harry Forrester then doubled Rovers’ advantage, before Theo Robinson completed the scoring.
The closest Yeovil came to scoring was when former Doncaster striker James Hayter hit the crossbar.
