Re: [Zope] Zope - future planning
Thanks to everyone for their comments and suggestions! I have decided to upgrade our Zope 2.6 application (which consists of 276 scripts/methods/external methods, 5 zcatalogs and 5 sets of zclasses) to Zope 2.9 and Five - as this appears to be a somewhat less painful migration than making a complete leap to Zope 3!

No, Zope 2 is definitely destined to slowly fade, but that is a process that will take years, and should have no real impact on your decision now. I'm not sure one should call it 'fade', but that's a debate about semantics. Right now, there's a lot of innovation going on in Zope 2 all the time. It's just that lots of that innovation is now shared with Zope 3 - Zope 2 and Zope 3 technologies are converging. This convergence will take many years to be "complete". We probably aren't even clear yet exactly what "complete" means, as both Zope 2 and Zope 3 will continue to evolve. So, besides porting to Zope 3 directly, you could port your application not to Zope 3, but to a modern version of Zope 2, such as Zope 2.9, and use the Zope 3 technology in it (a large part of Zope 3 is included, and Five is there to make integration possible). It allows you to evolve your application more gradually. It also allows your application more easy portability to Zope 3 if you should need to later, as you're already using the technology. Zope 2 is open source, so as long as there are users interested in maintaining Zope 2, Zope 2 will be with us. There are *lots* of users of Zope 2, so there is no reason to worry about it for years to come. We do think Zope 2 will very slowly, step by step, turn more into a special application of Zope 3 technologies, and the framework bits that were important once in Zope 2 will be replaced gradually with bits from Zope 3.

[Zope] Zope - future planning
I have a fairly extensive application running on Zope 2.6 and would like to upgrade it for long-term maintainability.

No, Zope 2 is definitely destined to slowly fade, but that is a process that will take years, and should have no real impact on your decision now. The question now is how much work you think it will be to upgrade to 2.9, vs how much work you think it will be to rewrite the applictaion to 3.2. And that depends in turn very much on what kind of site you are running, what third-party products you are using and no on. -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/ ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
