I stated my hope (at the bottom) that migration won't be too difficult.  
I (we) take migration issues very seriously!  Considering that the 
zope-cmf list has exploded with activity, it would be a terrible mistake 
to break compatibility now.  By releasing version 1.0, we made an 
implicit (as well as explicit) promise to retain compatibility.

That is yet to be determined.  This is not a project yet, nor even a 
proposal, just an informal RFC.

The tools will be a piece of cake to migrate IMHO; they just have to be 
called "services" instead of tools and have to be found a different way.  
The presentation layer will have more fundamental changes but I believe 
we can write a script that will migrate your customizations.
