On 13 August 2011, Nottingham Forest announced that Miller would sign a three-year contract with the club the following Monday. Miller's transfer from West Brom to Forest was finalised on Monday 15 August. The transfer fee was an initial £1.2 million. West Brom's Sporting & Technical Director, Dan Ashworth, stated: "This move is probably in the best interests of all parties because we can't guarantee Ishmael first-team football and this is a great opportunity for him to hopefully play regularly". Miller said about the transfer: "I have got a point to prove. I've had a few injury problems over the last few years...I need to go out there and show what I can do. I'm relishing the new challenge at this stage of my career".
