Burgess Hill moved into the second round with a comfortable home win against Sittingbourne.
And what really pleased manager Gary Croydon was that it proved his side are learning what is required at the new level.
He said: "Something drastic was needed after our FA Cup defeat at Boreham Wood but I'm surprised how quickly we've turned things round."
Tom Edmonds was drafted in to enable Julian Curnow to continue in midfield and Hillians generally gave new keeper Paul Stark a quiet afternoon.
However, he did pull off two quality saves from Jon Neal, the first immediately after Steve Harper had grabbed his second goal on 49 minutes with a hooked half volley.
In a bitty first half, Harper opened the scoring with a header from Matt Geard's cross on 20 minutes.
