The Cook Islands domestic champions won the qualifier event for the second straight year to confirm their spot in Group D later this month, alongside nine times champions Auckland City from New Zealand, Magenta from New Caledonia and hosts Solomon Warriors.
Tupapa head coach Delaney Yaqona said the biggest difference in the next stage would be the speed of play and technical skills of the players, meaning his team will need to lift their game.
"It's something we've been slowly preparing for. Obviously we need to speed our game up a bit more and have a bit more structure on the defensive side of things," he said.
"We're under no illusions. They're much better players than us and they've been playing top level football all the time so we've really got to pick our game up.
"We know we've got our work cut out for us but at the same time we're excited about it and we can't wait to get that tournament underway."
Tupapa players will have some brief respite before they resume training, with just under three weeks until their opening group match in Honiara, Yaqona said.
"Three games in seven days isn't an easy thing to do so it's about managing themselves and getting slowly back into training. I've given the boys about four days off and then slowly get back into it," he said.
"Going into this tournament one thing we want to focus on is our counter attack. First and foremost we've got to get all our defensive structures working right and then trying to get some goals through counter attack.
"If you look at all three teams they're technically very good - very good tactics and they're also very fast players," Yaqona said.
"It will be a massive challenge for us:.”
