Prepositions in a context , "of" vs "for"

Would you use "of" or " for" in the next sentences:

1- To arrange a soft transition of the authority and not a sudden one.

2-To arrange a soft transition for the authority and not a sudden one.

I mean to allow the movement of power from some one to another.

As the comments say, context is important.

1: We are moving the authority to sign checks from A to B; to arrange a soft transition of the authority...

2: We are proposing a re-organisation of the Valley Authority; to arrange a soft transition for the Authority...

It's a 'transition of' what's being transitioned, and a 'transition for' the agents affected by the transition.

PS: English being English, there are bound to be some exceptions.
