Rosenior was part of the Hull side that finished second in 2013 when the Tigers reached the promise land of the Premier League.
The Albion full-back is hopeful he can achieve that same feat with Brighton, who are third and behind leaders Burnley and second-placed Middlesbrough only on goal difference.
Brighton continue their push for promotion on Monday with an Amex clash against Derby County before their season comes to a close five days later at Boro in what is set to be a shoot-out for promotion.
Rosenior admits that knowing what it takes to go up in this league will serve him well in those final two crunch clashes.
He said: “When you have experience, it helps you to deal with situations that you’ve come up against before and it helps you to be able to give advice to others and their focus on their own performances.
“It’s been an immeasurable experience for me to be promoted with Hull and it was one I’ll never forget but I want to make sure I have more memories.”
Should Brighton end up in the Championship’s top-two or go up via the play-offs, Rosenior believes it would be the biggest achievement of his career, eclipsing reaching the Premier League with Hull.
He said: “It’s the best one – the next one is always the best one.
“I don’t like looking back on my career or what I’ve done, I want to do much more in the future as a player, as a coach, and maybe one day as a manager.
“The next one is the most important, so this one now would be fantastic and hopefully it will happen here with Brighton.”
