Linvoy Primus hailed the formation of Club 1898 and insisted: The club is sorry for the past.
The Pompey legend is part of the new group aimed at looking after the interests of former players.
In the past, the club have been criticised for their attitude towards those footballers who represented them over the years.
Now Primus sits on the Club 1898 committee, alongside fellow ex-players Vince Hilaire, Alan Knight and Pat Neil, among others.
For the 37-year-old, its inception is crucial in continuing to move away from the old regime.
The head of club liaison believes Club 1898 can maintain the good work of the new era.
Primus said: 'The organisation was mainly through Alan Knight, who was keen to bring old players from his era back to the club.
'Some had left under a cloud in terms of how the club treated them and didn't feel they could come back.
'These players have been hurt in the past. They might not have been Premier League players but should be recognised just as much as the Premier League team and FA Cup team.
'The current regime are not responsible for what has gone on before but want to rebuild bridges. So it has offered the hand of friendship and is sorry for what has gone on in the past.
'That's the nice thing about it. It's a new mindset here and there are people who want to do what is right. We have a responsibility to welcome back former players and staff – and this is a way we can do it.'
Primus will be present at the Scunthorpe game along with more than 40 other ex-players.
Since being given his new role at Fratton Park, the former defender has been instrumental in attempting to rebuild bridges among the community the club have let down.
And he still believes there is plenty of work to be done.
He added: 'It's about shaking off the shackles after the club very quickly disintegrated.
'If we have got certain foundations in place we can really cement a good culture. It is not a club PR stunt in any way.
'Club 1898 are going to raise funds through dinners, football matches and donate it to worthy causes.
'I think it is going to take a long time to rebuild all those bridges.
'But the club is doing something towards trying to help that happen.'
