The game is scheduled to take place at the Hive, home of Barnet FC, having already been postponed twice at nearby Boreham Wood in recent weeks.
But the teams are now set to finally meet and play for a spot in the quarter finals, where Manchester City wait to host the winners.

And Alex Morris’s side head south from Cheshire with the backing of first-team boss Steve Davis.
"It is something that they have been looking forward to and they will be well prepared," said Davis.
"Alex will have them well-drilled and will have worked on taking on players of that calibre.
"The original match was postponed due to the pitch being frozen in areas, so I know that Alex, Kenny [Lunt, assistant coach] and the boys have been eagerly waiting for it to come around."
As a club, Crewe have had a long history of producing young players who have gone on to represent the club's first-team before moving on to a higher level.
The likes of Danny Murphy, Dean Ashton, Nick Powell and David Platt are just a few of the players to have emerged from the Gresty Road ranks over the years.
And after seeing the young Railwaymen see off Fulham and Bolton Wanderers in the last two rounds as well as at close quarters on the training ground, Davis believes they could challenge the young Gunners.
"Getting through is not beyond them and if they can play as well as they have in the previous rounds then it will be a good spectacle," Davis told CreweAlex.net.
"I have been impressed with them, they are all comfortable on the ball and there is a good balance to them.
"As a team they have been doing well and as individuals, there’s always a few that stand out."
The tie kicks-off at 7pm at the Hive, with free entry for supporters.
