But tonight it's back to Fratton Park as the Blues'Â history-making drive is put on hold.
The comfortable 4-0 triumph over Maidenhead marked an 11thÂ match undefeated on the road for Kenny Jackett's men this season.
It continues to strengthen the best sequence of away results in Pompey's 98-year Football League presence.
Next up on their travels is the League One trip to Scunthorpe (November 24), who overcame Burton 2-1 in the FA Cup at the weekend.
In the meantime, Jackett's side face Spurs under-21s in the Checkatrade Trophy tonight (7.45pm) having already qualified for the next round.
A brief distraction ahead of far more important challenges lying in wait.
Pompey's boss said: '˜I'm told we have club-record away form '“Â andÂ I certainly hope that one continues.
'˜We have to take the confidence from what we've done, because we should. The players should take confidence from where things have gone for them.
'˜They must be humble enough to realise they've had to work hard for that, it hasn't been plain sailing.
'˜You have to maximise everything you do, be right at the top of your game all of the time and, if you can, build momentum and hopefully confidence.
'˜We've kept it consistent in terms of our approach home and away.
'˜Our working week, the way we set up for the game and the team talks '“ there is nothing different home or away.
'˜Our away form is maybe just the way things have worked out.'
Pompey have already qualified from Southern Group A in the Checkatrade Trophy, while second-placed Spurs are well placed to follow.
The Blues have lost twice at Fratton Park so far this term '“Â AFC Wimbledon in the Carabao Cup and Gillingham in League One.
In contrast, it's nine wins andÂ two draws on the road.
Jackett added: '˜People have different theories that sides come and sit in when they travel away.
'˜But I don't think too many sides have sat in at Fratton Park.
'Gillingham beat us and played two up front the whole game, Burton was a tight one and they attacked us as well.
'˜I don't think there's that much difference home or away.'
