The superstar batsman is set to commute his four-month England and Wales Cricket Board contract into a full annual one, having satisfied his employers that all is well again after his summer of discontent.
Team director Andy Flower was central in the peace-making process and he said: "We did move on from it as soon as we had our meetings and everyone made a commitment to do so. I want to continue that, moving forward."
Pietersen agreed a four-month deal at the end of September, in order to take part after all in the Test tour of India - which ended on Monday with a historic first series victory here since 1984-85.
Flower anticipates no further problems, after Pietersen played a full and important part in England's success on and off the field. He is mindful that lessons can be learned from past problems, and their solutions, but is not inclined to dwell on them.
Flower added: "We want to learn from the past, but we don't want to keep on revisiting it. The contract won't be a problem. Kevin has been excellent in every way. We don't all always get on with people all of the time - any of us in any walk of life - and everyone has made an effort to make it work.
"It's been really good fun and he should be very proud of the way he's operated out here both as an individual and as a player."
Pietersen's masterful hundred in Mumbai was the man-of-the-match performance in a comeback victory which set them on the way to their unexpected series success.
"In Mumbai he showed real skill in Indian conditions on a pitch that turned on the first day," added Flower. "For him to score as quickly as he did there and put such pressure on the opposition bowlers really helped us turn the series around.
"He also scored a 73 and, I think, a 54 in the series - important innings - and he's been excellent in the field and in the dressing room."
