Leyton Orient have reached an agreement with the Premier League allowing West Ham's use of the soon to be refurbished Olympic stadium.
Leyton Orient live updates
Rotherham came from two goals down to win promotion to the Championship after a dramatic penalty shoot-out at Wembley.
Leyton Orient appeared to be in control when Moses Odubajo and Dean Cox struck in the space of five minutes to give the O's a 2-0 lead at the interval.
But Alex Revell pulled a goal back for Rotherham with a tap-in from a free-kick, and the 30 year-old levelled matters in stunning fashion five minutes later, volleying over Jamie Jones from outside the area.
After tiring half hour of extra-time, Rotherham's Lee Frecklington saw his spot kick brilliantly parried by Jones, while Adam Collin denied Orient's Mathieu Baudry.
Substitute Chris Dagnell, Orient's fifth penalty taker, needed to score to keep the O's alive, but his shot was saved by Collin.

Moses Odubajo's goal earned Leyton Orient a 1-1 draw at Peterborough in the first leg of their Sky Bet League One play-off semi-final, after Britt Assombalonga's 33rd goal of the season gave Posh the lead going into half-time at London Road.
Leyton Orient's Sky Bet League One clash with Bristol City at the Matchroom Stadium on New Year's Day has been postponed due to structural damage to the stadium.
The adverse weather conditions over the festive period has left the floodlights requiring repair work.
A Swindon fan arrested after running on to the pitch and allegedly punching Leyton Orient goalkeeper Jamie Jones has been released on bail.
Orient boss Russell Slade said that, although 24-year-old Jones was unhurt, he was angered by the incident, which Slade described as the worst he had seen since becoming a manager.
