Converting to a new traditon, what sort of roleplaying and game mechanics apply Options

[loadsol]

I'm a big fan of magic in shadow and i find the differnt tradtions of magic in the system very interesting. So i was wondering about what sort of role playing and if needed game mechanics needed for a magic character wanting to change his tradition. I figure it works in away sort of like a character converting to a new religion, i.e. much time and dedication and using methods apropriate. I figure this more of a roleplaying area but i think some game mechanis apply like the aquisitons of new spirit types, or geas, or what happens if a bound spirit type a character has isn't included in his new tradition. Also what by this extent how would a character switch mentor spirits.
