You seem to not know that...
Sports Interactive made Championship Manager between 1992-2004
Sports Interactive fell out with game publisher Eidos in 2004
Sports Interactive took the game code and mechanics behind CM and made Football Manager 2005 and FM06, FM07, FM08, FM09 and FM10
Eidos only had the brandname "Championship Manager" left and gave it to developers Beautiful Game Studios to make in 2004.
Therefore any CM made after 2004 is NOT related to any CM before 2004. CM started from scratch in 2004.
FM10 however has a direct linkage to every CM from 1992-2004 and every FM from 2004-2010
