Here's what those closest to the action had to say about the winÂ at York Road.
Â We had good control of the game right the way through and put a lot of good balls in to the box in the first half.
Tom Naylor hit the crossbar but their one moment at 0-0 was when they hit the post - after that we went onto get what was a key goal before half time.
It was a good left-foot cross from Ronan Curtis and Ben Thompson finished it.
We did what we needed to do in the second half.
Going down the hill we needed to make sure our fitness told and we got control of the game, which we did.
We needed to go away from the opposition, if we could.
I was pleased seeing the second, third and fourth goals going in, it got more comfortable.
It turned in to a very professional job for Portsmouth.

When the second goal goes in the confidence just drains away from them.
I'm not going to complain about it. It was a great occasion for us.
First half I thought it was quite a competitive game. When they score just before half-time it kills us a little bit.
They then got the second early in the second half.
The first half was a bit shaky at times, they got into the game and we were on the back foot a little bit at times during spells.
To put the side ahead with the first goal was a great feeling and we kicked on from there.
The second half was a bit easier for us '“ and we came here and did the job.
MaidenheadÂ caused us some problems, we caused them some problems and it was quite a close encounter in the first half, we were patient and got the result we needed.
They hit the post, they came close, who knows if that goes in it could have changed the game.
But at the end of the day we got the win and are through to the next round and that's all that matters '“ that's what we came here for.'

Pompey eased to victory over non-league Maidenhead to progress in the FA Cup.
Yet it was a tight contest before Ben Thompson intervened on 43 minutes to crucially break the deadlock.
After that it was all Pompey and there could have been more than than subsequent 4-0 scoreline.
So no cup upset as a strong Kenny Jackett line-up deservedly cruised past their hosts.

Pompey continued their fine start to the season by recording a first FA Cup victory since 2016 against Maidenhead United.
It could have been a potential banana skin for the Blues but they came through with ease.
Struggling Magpies struck the post through Ayo Obileye when it was scoreless.
However, Ben Thompson's first Pompey goal made all the difference twoÂ minutes before the break.
That effort seemed to take the wind out of Maidenhead's sails.
Then goals from Oli Hawkins, Jamal Lowe and substitute David Wheeler wrapped up a routine Cup victory.
