Assistant coach Franck Azema and Leinster coach Jono Gibbes are set to lead Clermont next season.
Current Clermont boss Vern Cotter will leave Les Jaunards to take over as head coach of Scotland.
Azema currently is the team's backs coach and he will be promoted to head coach. Gibbes has worked under Joe Schmidt at Leinster as forwards coach and will join the French club as assistant coach.
Esteemed coaches Robbie Deans and Jake White have both been linked with the position, but Clermont have confirmed that they have decided to look within their coaching staff for a new boss.
Cotter will leave the club a legend after guiding Clermont to their first ever Top 14 title in 2010, winning on the 11th attempt.
Gibbes won eight caps for New Zealand during a player career where he also captained the New Zealand Maori, before joining Leinster in 2009.
