If anyone in the Rotherham camp is getting too giddy at the prospect of a launching an instant return to the Championship, they will have to listen to Darren Potter’s cautionary tale.
The Millers are hoping to bounce back from their miserable campaign last year by mounting a League One promotion bid, though boss Paul Warne has tempered expectation by saying he would be happy with a top-10 finish.
Potter arrived at New York Stadium in mid-June and finds himself in a similar position to that of 12 months ago, where MK Dons were returning to the third tier, hoping their stay would just be a season long.
Things did not pan out that way, though, as the Dons limped to a 12th-placed finish in a campaign of overhaul as long-serving boss Karl Robinson and number two Richie Barker left their positions.
That experience has at least made Potter battle-ready and having said that the Dons thought League One was going to be easy last year, he is not prepared to allow the same thing to happen at his new club.
“We came back into League One thinking we could come straight back up and we got a bit of a shock to be honest,” the 31-year-old conceded.
“It proved a lot more difficult than we thought, we were a lot further down the table than we anticipated than we ever would be.
“It was a wake-up call but hopefully I can use my experience of that and implement it going forward.
“League One seems to be getting stronger each year, but I am sure the lads are relishing getting back into training and getting going.”
Despite his words of caution, Potter has not come to the Millers for another season of mid-table mediocrity and will impart his experience of many games at League One level.
“Hopefully we can hit the ground running and get some early points on the board and hopefully we can be up there challenging,” he added.
“I have racked up a lot of games now in the division, got a lot of experience and hopefully I can put that to good use and help the youngsters in the squad and be a vital part of the team going forward.
“Promotion is certainly what I will be aiming for, it is one of the reasons I have come.
“I want to help us jump straight back up, you have to be ambitious and set your sights high and that is certainly what I am doing, I want to come in there and try and help a winning environment.”
