I know they are completely incompatible (this is almost the first thing that is said on the Zope3 homepage). And that's why I am worried. Because if Zope 3 is the future of Zope, then at one point everyone will have to use it (and stop using Zope 2). I was asking if there was some documentation about "best way to rewrite zope2 extensions for zope3". Maybe I did not get you right : are you saying something like "they are so incompatible that there will never be a CMF product for Zope 3 ?"

Hi all,
I would like to know if now is already the right time to migrate a website that uses : + Zope 2.7 + CMF + TranslationService,Localizer + in-house Zope 2.7 products (extending CMF) ...to Zope 3.
Is CMF already available for Zope 3 ? Is there any documentation for doing so ?
Also, are there available benchmarks that compare out-of-the box Zope 3 performance compared to Zope 2 ?
Thanks a lot.

I am pretty sure that Plone, CPS and all other CMF-based applications will move to Zope 3 at some point but they will not be based on CMF for Zope but based on *something* that has some related functionalities but this will not be CMF and it will unlikely compatible with CMF. -aj --On Montag, 8.

Zope 2 is completely incompatible with Zope 3. Best to look at Stephan Richter's Zope 3 book (dev.zope.org -> Zope 3).

No, wait, Zope 3 hasn't come out yet. What *has* come out is Zope X3 3.0.0.0. That's _different_. X3 is not compatible at all with 2. It is a waypoint on the roadmap to a non-X3 Zope 3 release which will be far more compatible with Zope 2. In other words, this is a purely experimental release featuring no compatibility capability. It is not meant to be "how Zope 3 will be." At least, that's my read of their statements. -roy

It is different, but not as different as you make it sound. Personally, I am not that optimistic as others about providing compatibility layers, simply because it is not possible. :-) However, I believe in a smooth transition from Zope 2 to Zope 3. I think the Five project is the leading example, since it allows you to design applications that run on both platforms today. Also, I think eventually, once all the CMS actors get their act together, we will also have a very cool, new CMS framework; I doubt it will be CMF compatible...is that even desirable?
