Newport Gwent Dragons boss Lyn Jones says his side aim to continue their "carefree" European Challenge Cup away form in the semi-final at Edinburgh on 17 April.
"Our away form has been great and we'll be looking for a carefree performance," said ex-Wales flanker Jones.
"We won't be putting too much pressure on the players."
The Welsh region were well beaten 24-10 on their last visit to Edinburgh in the Pro12 in October.
But Jones believes his side have made big improvements from their injury-hit "shambles" of a performance on that occasion.
"It was nil-nil after half an hour and we lost our way after that, but we're a far better unit now than we were then," he said.
"But Edinburgh have also improved as the season's gone along.
"They've made a decision to recruit from the southern hemisphere rather than go to their academy, so they've got lots of well-developed players who are going to be a threat and don't make many mistakes.
"We need to go up and be positive - it's a semi-final I know but we'll be looking to open up the game," he told BBC Wales Sport.
The Dragons have never reached a final, defeats in Clermont in the last four of the Challenge Cup in 2007, and in Gloucester in the Anglo-Welsh Cup in 2011 the closest they have come.
They are unlikely to have Wales lock Andrew Coombs available after he left the field with a serious leg injury early in their quarter-final victory over Blues.
But Jones hopes James Thomas, who was also forced off after moving up to the second row, will pass concussion tests this week.
Previous stand-in captain Rynard Landman remains suspended for the Murrayfield trip after his red card against Connacht in the Pro12.
