Blue Square Premier champions Aldershot have already secured their place in the Football League for next season - but who will join them?
Cambridge United, Torquay United, Exeter City and Burton Albion will battle it out for promotion in the play-offs.
Forest Green boss Jim Harvey, whose side took points off all four teams this season, weighs up the strengths and weaknesses of each of the semi-finalists for BBC Sport.
And the former Northern Ireland assistant manager, who lost at the semi-final stage with Morecambe in the play-offs in 2003, also predicts who he thinks will emerge victorious from the final at Wembley on 18 May and take their place in League Two.
EXETER CITY V TORQUAY UNITED
Exeter-Torquay: Date: Thu 1 May Kick-off: 1945 BST Venue: St James Park Torquay-Exeter: Date: Mon 5 May Kick-off: 1945 BST Venue: Plainmoor
The local rivals have set up two more mouth-watering derbies with Exeter, managed by Paul Tisdale, having home advantage in the first leg against the FA Trophy finalists.
Paul Buckle's Torquay, looking to bounce straight back into the League at the first attempt, and Exeter, beaten play-off finalists last season, shared a win apiece when they clashed over Christmas and the New Year.
HARVEY'S VERDICT:
"Exeter have the momentum and their football has been very consistent since Christmas.
"They have got a good run together. They have been playing good stuff and picking up results, as opposed to Torquay who have maybe gone off the boil a little bit.
Chris Zebroski has scored 18 goals for Torquay this season
"They started the season very well but are very direct and I think teams found a way to cope with them.
"It's been a bit stop-start for them recently and I think they will have their work cut out to hold Exeter over two legs.
"There will be a lot of pressure for both clubs to perform and sometimes form does go out of the window and you need that bit of luck.
"But if you have got a bit of form and you are passing the ball well you have a chance of making it happen.
"Torquay have got match-winners. They are always powerful at set-pieces and capable of pinching a goal that way, but Exeter are playing the better football.
"Exeter have made very few changes and have a system that's very reliable for them.
"They have been more solid and consistent in the run-in and they must be feeling better about themselves. They have also got that experience of last year which will stand them in good stead.
KEY MEN:
Exeter: "Richard Logan scores goals and Adam Stansfield has come back into it and he is more than capable.
Torquay: "Chris Zebroski has had a good season for them and from set-pieces Tim Sills gets his head on a lot of stuff. Lee Phillips is a real work horse going back to his old club who will be looking to do well, as long as he doesn't try too hard."
Nigel Clough's Burton, the only club without a Football League history, have made it to the play-offs for the first time and meet a Cambridge side re-vitalised under Jimmy Quinn and seeking a League Two return after a troubled couple of years.
Cambridge had the edge in their two meetings this season with a win and a draw helping them finish as runners-up to champions Aldershot Town.
HARVEY'S VERDICT
"A bit like Torquay, Burton have struggled a bit to hang in there. They picked up some form but recently you just wondered if the pressure was beginning to tell and that the season might be catching up with them.
"We beat them 3-1 and then they lost 4-1 to Kidderminster, although they have had a little break to get themselves ready.
"Cambridge are a solid team which relies on clean sheets and 1-0 wins. That's the way they set up.
"It's not enjoyable to watch but they are hard to break down which makes them hard to beat at this stage of the competition.
Nigel Clough will be hoping to guide his Burton side to promotion
"There's not a lot to go wrong for them. They defend all day and they have one or two players who can score goals and from set-pieces they are a threat.
"I think Burton might have to work too hard and it might just catch up with them. Their form suggests they might not be too confident and they do concede goals.
"I would like Nigel to go through. He has been there a long time and has kept digging away and is a nice lad.
"They have got ability and some good players. They have good wingers in John McGrath and Keith Gilroy who will put the ball in for Daryl Clare and Shaun Harrad, who score goals, so they have got that in their locker.
"But if you classed it as a boxing match Burton would be the boxer and the other boys would be the street fighters and I think the punch will come from Cambridge, the brawlers."
KEY MEN
Burton: "Clare will always score goals to given them a chance."
Cambridge: "Cambridge rely a lot on their defence and Danny Potter is a good goalkeeper."
OUTCOME: Cambridge to go through.
FINAL
Date: Sun 18 May Kick-off: 1600 BST Venue: Wembley
HARVEY'S VERDICT: "The final is at Wembley which will be a good surface to play on. It's also a big pitch which could make it a more open contest.
"Exeter experienced it last season and I would like them as the footballing team to through."
