So we’ve taken a little trip down memory lane to recall the last time the Dons celebrated promotion to the Championship in 2012.
Tony Miller’s side won the Championship One title and then completed the double by beating Barrow in the play-off final at Warrington.
Here are some of the best photographs from the celebrations at Warrington and the subsequent civic parade.
We will have live updates of Sunday’s final here at www.doncasterfreepress.co.uk from 1pm.
