It looks likely that Boston United will be set to face five new opponents in the Skrill North next season.
Chester FC, Hyde FC and Tamworth appear ready to join the Pilgrims following their relegations from the Skrill Premier, with fellow bottom-four side Dartford set for the southern section.
Meanwhile, Chorley and AFC Fylde will move into the division, after winning promotion from the Evo-Stik Northern Premier League.
Chester and Hyde are the previous two Skrill North champions, but both struggled in non-league’s top flight last season.
Boston faced Tamworth in the FA Trophy last season, leaving the Lamb Ground on the receiving end of a 2-0 defeat.
Chorley won the Northern Premier title, pipping FC United of Manchester by a point.
Fylde won the play-off final, beating Ashton United on penalties when keeper Ben Hinchcliffe slotted away the winning spot kick.
Leaving the division will be AFC Telford United, who won promotion to the Skrill Premier.
They will be joined by either Guiseley or Altrincham, who will meet in the division’s play-off final on Saturday.
Histon, Workington and Vauxhall Motors will all drop out of the division.
Oxford City also finished in the bottom three, but have earned a reprieve after Vauxhall Motors applied to move down a division to save on costs.
However, with Lowestoft winning the Ryman League play-off final, they may move north with Oxford switching south.
