As I've pointed out before, porting old stuff is really not the issue. 
People tend to not touch working systems. Why should they?

So I'd really focus on making Zope 3 a great product, not on backwards 
compatibility. On of the lessons we can learn from aD is that we should 
not heavily invest in porting stuff.

I don't think the Zope 3X API is stable enough right now to actually be 
able to see all the problems with migration. For me it is important that 
the content/data can be migrated, and that should be no real problem. 
The applications will either be kept in Zope 2 or ported in the process 
of a new feature release.

The main issue is to quickly enable people to write code that will 
basically run on both platforms (new code that is). Time I invested in 
old code is not lost: I can still run it on Zope 2. But time I invest in 
new code for Zope 2 that can not be ported easily will be really lost ...

Maybe we should not call the new beast "Zope" at all ;-) Then there 
would be no problems with numbering ...
