Gabor Gyepes and Therry Racon will not be at Pompey next season.
But Yassin Moutaouakil and Phil Smith have agreed new Blues deals.
And they will this week be followed by Simon Eastwood and Dan Butler as Guy Whittingham’s squad begins to take shape.
Gyepes and Racon were key members of Pompey’s remarkable resurgence during the last few months of the season.
Yet defender Gyepes has now returned to Hungary and feels he will be able to earn just as much in his homeland without the need to uproot his young family.
In addition, Racon, who was on loan from Millwall but is now a free agent, priced himself out of a move after asking for an unrealistic £4,000 a week.
Whittingham is still awaiting answers from Johnny Ertl, David Connolly and Ricardo Rocha.
Ertl is currently backpacking in the Philippines for three weeks and Pompey remain confident the captain will sign when he returns to England.
In the meantime, Moutaouakil will this week sign his contract he has verbally agreed.
Former France under-21 international Moutaouakil grew impressively after an indifferent start at Fratton and made 19 appearances.
He made the right-back role his own after joining from Blue Square Bet South side Hayes & Yeading.
Keeper Smith, who has been with Pompey since December without featuring in a competitive match, signed a new deal on Thursday.
Of course, as revealed by The News last week, Patrick Agyemang will officially link up with the Blues on July 1 when his existing Stevenage deal expires.
It promises to be a busy week on the player front, with as many as three new faces potentially undergoing medicals on Thursday.
Whittingham has spent the past week negotiating with a number of targets as he seeks to assemble his squad well ahead of pre-season.
More talks will be held at Fratton Park today with several targets and their agents. In addition, midfielder Matty Blair had discussions with the Blues boss last Thursday as his expected move nears.
Blair, who has left York, is one of a number of wide players Whittingham is looking to bring in to his set-up for next season.
This week will also see Eastwood and Butler given long-term deals, the pair having blossomed with regular football this term.
Fellow squad members Shaun Cooper, Sam Sodje and Liam Walker also remain on Whittingham’s radar.
The Pompey boss has indicated he would like the trio to stay, although that will largely depend on how his recruitment drive develops over the summer.
John Akinde will also be given the opportunity to remain, but Whittingham is looking at other striking options.
Jed Wallace, Ashley Harris and Adam Webster are already contracted for next season, having penned deals before the Blues’ latest administration.
