The British fighter confirmed his split with trainer Don Charles earlier this week and Jones says the move stems from Dubois' desire to get back to the top instead of being a slight on Charles - who helped the boxer become IBF world heavyweight champion with a fantastic win over Anthony Joshua last year.
He told Sky Sports: "I've been around Daniel for just over a week. He's decided he needs a fresh team - a new voice, a new plan. But that's not to diminish anything Don Charles has done. He's done a fantastic job.
"They shared some incredible nights. The AJ fight at Wembley was iconic, and Don played a massive role in that. But this is life - Daniel felt he needed a change, and that's what's happened."
Jones is overseeing Dubois' route back to the elite following his loss to Usyk last month and the end goal is to make the fighter a two-time heavyweight world champion.
He said: "Daniel just wants to win boxing matches. He's a fighter through and through.
"He was upset with his performance against Usyk, he thought he could do a lot better. But there's no shame in losing to the greatest heavyweight of this era. He's undoubtedly the best of this generation.
"Daniel's lost to him a couple of times. He lost to Joe Joyce when he was very young. There's no shame in that. He's a former world champion, and now the sole focus is becoming a two-time heavyweight champion of the world."
Jones explained that Dubois has a range of options for his next opponent and believes that a bout against rising star Moses Itauma is inevitable following the prospect's crushing win over Dillian Whyte last weekend.
He said: "100 per cent. That fight [with Itauma] is going to happen. Daniel's 27. Moses looks like a phenomenal talent at 20. These boys are going to be the future."
Jones is also open to Dubois taking on Joshua in a rematch.
He said: "The rematch with AJ is always there. I'm a big AJ fan - I've made no secret of that.
"He's a proud man, and I know he won't want to keep seeing that knockout by Daniel on his screen. I'm sure he'll want to right that wrong. And if he ever wants to, then let's get it on."
