Aberdeen proved they have the bottle to add to their 2014 League Cup trophy success by holding their nerve at Easter Road.
Hibs created the most chances in a tense quarter-final but that will not be remembered when the Reds run out at Hampden on the weekend of October 27-28.
Ultimately all that matters in cup competition is progressing.
The result is primary, even if it is 6-5 on penalties, performance secondary.
Aberdeen had the organisation, fitness levels, discipline and ultimately the nerve to come through what at times was a Hibs onslaught.
Last season the Dons triumphed in a Scottish Cup quarter-final penalty shoot-out at Kilmarnock only to crash to Motherwell at Hampden in the semi. This time it must be hoped they use this as a catalyst to push on.
Triumphing in penalty shoot-outs is all about having the belief and confidence to bury the ball and the skill to do it.
Aberdeen have been Scotland’s second best team for the vast majority of the five and a half years McInnes has been at the helm.
They have secured four runners-up finishes in the Premiership but there is only the solitary League Cup trophy triumph in 2014 from that period.
For all the plaudits for the consistency of finishing second trophies are what fans want, and what are remembered.
Aberdeen are now just two wins away from silverware and will unlikely face a tougher challenge than Hibs away.
It was the Reds who created the opening chance in the third minute when Andy Considine’s shot from 10 yards out hit Mark Milligan before being scrambled away.
Soon after the dangerous Florian Kamberi rounded keeper Joe Lewis only to shoot into the side netting.
Then Emerson Hyndman skewed a 15-yard shot wide before Gary Mackay-Steven followed suit by firing off target.
Following impressive play, on-loan Manchester United striker James Wilson was fouled by Mark Milligan. From the free-kick Dom Ball curled a superb 25-yard effort that rattled the crossbar and bounced inches from the line.
It should have been the catalyst for an Aberdeen onslaught but instead it was the home side who controlled the rest of the half.
In the 36th minute Martin Boyle, who had a goal chalked off minutes earlier for hand ball, burst past Max Lowe into the box only to blast wide with the goal beckoning.
Hibs were turning the screw and Lewis saved from Shaw at the near post in the 42nd minute with Kamberi then shooting over soon after the break.
The increasingly busy Lewis produced a superb, and brave, close-range block at the near post to deny Hanlon.
As the high tempo continued Wilson fired in a low left-footed 30-yard drive but Bogdan comfortably saved.
Hibs should have gone ahead in the 85th minute when Shaw was played clean in by Hyndman but he blasted wide.
In extra time it was the Dons who wasted glaring opportunities when substitute Stevie May was played through the offside trap by Chris Forrester. May hesitated with his shot before firing it across goal and wide.
Moments later McGinn missed an even clearer opportunity when through only to blast over.
Hibs were denied in the 104th minute when a flicked header from Ryan Porteous was cleared off the line by Considine.
The penalty drama was played out in front of the vocal Aberdeen fans in the South Stand.
Captain Graeme Shinnie comfortably netted before Lewis superbly saved from Stevie Mallan.
It was all square when McGinn’s spot-kick was saved. But the Reds secured a spot at Hampden when Thomas Agyepong’s penalty hit the bar.
