"We don't want to go into the Championship being naive," O'Driscoll told the official club website.
"I think we are trying to be realistic without being negative. It's a big jump financially and we've found that out already, but we've got a team who have played together and we've got a good reputation of trying to do the right thing.
"It could be a bit of struggle but the likes of Bristol City have pointed the way last year and showed you what a bit of confidence and a bit of belief can do.
"We have a group of players who came to Doncaster really to play in the Championship and now they've got that opportunity so there's a great challenge for them all."
