Walton Casuals will host Molesey and Canvey Island in the early rounds of the FA Cup and FA Trophy.
The Stags will kick-off their cup campaigns a week after the league opener, with league rivals Molesey the visitors on Saturday 19 August.
Anthony Gale’s side equalled their best ever finish in the competition last season, before defeat at Westfields in the Third Qualifying Round. The Moles crashed out in the Preliminary Round with a 2-0 defeat to Godalming Town.
The two clubs also met in the FA Cup Preliminary Round in 2008. Goals from Matt Weston and Craig Lewington earned a 2-0 win for the Casuals at Walton Road Stadium.
The Casuals will then host Bostik North side Canvey Island in the FA Trophy Preliminary Round on Saturday 8 October.
The recently relegated outfit began their cup campaign in the First Qualifying Round last season, but fell to Enfield Town at the first hurdle. The Stags also suffered an early exit at Hythe Town.
A trip to Northwood or Maldon & Tiptree awaits the winner on Saturday 28 October.
