Last term was deemed by many as a transitional one for the Blues, as Danny Cowley put his stamp on the team he inherited.
However, that wasn’t the case for a swathe of familiar ex-Fratton Park faces, who will be playing in a higher division come August following successful campaigns with their new clubs.
But who are they? And where did they find success?
Here’s all the former players to wear royal blue who won promotion last season.
5. Rasmus Nicolaisen - Toulouse
Following his Pompey loan, the centre-back joined Toulouse in 2021 and immediately gained success in France. Last term he made 36 appearances as they gained promotion to Ligue 1, where he'll find himself up against Messi, Mbappe & Co at PSG next season. Picture: Martin Rose/Getty Images Photo: Martin Rose
6. Michael Smith - Rotherham
The ex-Pompey striker fired Rotherham back to the Championship last season by scoring 25 goals in all competitions. However, with his contract set to expire, his Millers future is unclear - with a swathe of clubs interested in signature. Picture: George Wood/Getty Images Photo: George Wood
7. Luke McGee - Forest Green Rovers
After making 44 league appearances for Pompey, McGee joined Forest Green Rovers via a Bradford loan spell. The goalkeeper made 48 appearances last season and lifted the title alongside promotion back to League One. Picture: Nathan Stirk/Getty Images Photo: Nathan Stirk
