Comitis recently completed his purchase of Mpumalanga Black Aces and has confirmed that the club would be relocating to the Mother City.
Aces have kept just 15 players from the side that did duty in the 2015/16 season, and KickOff.com has learnt that Moon is one of those.
The 34-year-old former Bafana Bafana right-back joined Aces in January after terminating his contract with Mamelodi Sundowns and made 17 League appearances.
Moon started his career with Comitis at Ajax Cape Town as teenager back in 2005, making 72 appearances for the Urban Warriors.
He also played for the likes of SuperSport United, Golden Arrows and Platinum Stars, and had stints in Greece with Panathinaikos and PAOK.
