No. CC will auto convert from one Millenium 3 to another Millenium 3. So it'll work on any combnination of Luke, Laura, Matt, Maddie, M3, V3, SP, A3, Hiro, etc. It will also autoconvert Dodger's Aeon line since they're based on Mil3 products. It will not autoconvert on anything below, so you have to do it by hand on V2/M2/Kids/P4, etc.
