The SA rivals played three quarters of 28 minutes each with first-choice teams at Mt Barker in the Adelaide Hills on Friday night.
Three more terms were to follow featuring lesser lights as the majority of frontline players were rested.
After three quarters in the full-strength phase, the Crows were well ahead, 14.5 (89) to 8.9 (57).
Soligo booted three goals, set up another and collected a swag of disposals.
The 22-year-old on-baller, who finished third in the club champion award last year, was particularly influential as the Crows blew Port away in the first two terms.
Soligo, Riley Thilthorpe and Taylor Walker, entering his 18th AFL season, kicked two goals each in the initial two quarters when the Crows led 11.4 (70) to 5.5 (25).
Thilthorpe, like Soligo, finished with three majors and flourished against an under-sized Power defence missing tall backmen Esava Ratugolea and Brandon Zerk-Thatcher.
Ratugolea is in doubt for the start of the premiership season because of a knee injury while Zerk-Thatcher's return from a back injury remains uncertain.
Adelaide gave unofficial debuts to Sid Draper, who was pick four at last year's draft, and recruits James Peatling, who has shifted from GWS, and ex-Melbourne forward Alex Neal-Bullen.
Peatling and Neal-Bullen had some promising patches and Josh Rachele kicked two goals.
Port's prized draftee Joe Berry, who was selection No.15 last year, impressed with some clean ball-handling.
The Power's ex-Collingwood goalsneak Joe Richards booted one goal while former Gold Goast forward Jack Lukosius was quiet, but converted one trademark long goal with a sweet strike from 50 metres into a blustery breeze.
Power stalwart Darcy Byrne-Jones slotted three goals and set up another for captain Connor Rozee while Jason Horne-Francis was prominent in the midfield, as was Miles Bergman in defence.
