Pompey have been drawn away to Championship side Cardiff in the first round of the Carabao Cup.
The contest will take place at Cardiff City Stadium in the week beginning August 8, with confirmed details and ticket information to be announced in due course.
The tie means there will be an instant return to south Wales for new Pompey signing Marlon Pack.
The sides met at the same venue in this stage of the competition in 2017, with the hosts needing extra-time to progress.
Pompey exited the Carabao Cup to Championship opposition in the first round last season, narrowly losing 2-1 at Millwall.
Cardiff saw off Sutton to make it round two, where they were knocked out by top-flight Brighton.
