The East Londoners laid on a blockbuster show afterwards as the curtain fell on their home of 112 years.
Fireworks, video tributes, interviews and the return of legendary players from a bygone era made it a night to remember for all involved.
And West Ham will now embark on their big move to the 60,000 seater Olympic Stadium this summer with a record 52,000 season tickets holders in tow - second to only Manchester United.
While those season ticket sales are proof enough that the majority of Hammers fans back the move, there is still some trepidation over how it will pan out long term.
One of the key concerns for many West Ham fans is the unknown element and fear of losing their intimidating and famous atmosphere.
'It's weird this move'
Now former Hammers hero Martin Allen has put the club's heart-wrenching move into his own words with a great analogy.
"It's a bit like dumping your girlfriend because she may be getting a bit old and leaving her for a new, younger, better looking model," Allen said, as reported by the likes of The Sun.
"But while she may look the part, you don't know what she's really like as a person and that's the risk.
"It's weird this move. All those routines built up by generations of families are going.
"It's going to take time for it all to settle down."
Mad Dog speaks from the heart
Allen's words carry some weight with Hammers fans given he scored 25 goals in 190 games in the claret and blue between 1989 and 1995.
He was affectionately nicknamed Mad Dog by supporters and has always kept a close eye on his old club in his role as a football pundit away from his work as a manager.
As a player Allen always wore his heart on his sleeve for West Ham and nothing much has changed as he speaks from the heart about the club to this day.
