Relegated Wigan will start their 2020-21 League One campaign away at Ipswich.
The Latics had finished 13th in the Championship last season but a 12-point penalty for going into administration saw them return to the third tier.
Other relegated sides Hull and Charlton face trips to Gillingham and promoted Crewe respectively.
League Two champions Swindon host Rochdale, while fellow promoted clubs Plymouth and Northampton start at home against Blackpool and AFC Wimbledon.
Sunderland will start their third consecutive season in League One against Bristol Rovers at the Stadium of Light.
The season will start behind closed doors on Saturday, 12 September - six weeks later than scheduled because of the Covid-19 pandemic - with League One clubs playing their first competitive games a week earlier in the Carabao Cup first round.
Clubs will play 11 rounds of midweek league fixtures - up from five that were initially scheduled for last season - with the campaign set to finish on 8 May, just a week later than normal.
A majority of third-tier clubs voted to curtail the 2019-20 campaign in June, with final positions decided on points per game.
Matches at the start of the 2020-21 season, which officially begins on 5 September with ties in the Carabao Cup first round, are to remain behind closed doors because of the ongoing impact of the pandemic.
However, Charlton Athletic have said their home game against Doncaster on 19 September is "likely" to be used as a crowd pilot test.

Wigan and Charlton battle off-field troubles
While sides relegated from the Championship are often tipped to bounce straight back at the first time of asking, Wigan and Charlton have had tumultuous summers and have issues which are yet to be resolved.
Managerless Wigan were put into administration on 1 July by then owner Au Yeung Wai Kay, just weeks after buying them, with administrators setting a deadline of 31 August to sell the club - hinting the Latics may not be able to start the new season if a deal is not completed by that date.
Their first home league game will be at an empty DW Stadium against Gillingham on 19 September.
Charlton have had ownership troubles of their own, with the English Football League rejecting a takeover attempt earlier this month, though prospective new owner Thomas Sandgaard is now in talks with various elements of the Addicks' complicated ownership structure.
After their opener at Crewe Lee Bowyer's side welcome Doncaster to The Valley.
