Zope 3 is not backwards compatible with Zope 2. There will probably
not exist an *easy* way to "migrate" as such. People are slowly
working on merging the frameworks so that it will be possible to run
both Zope 2 and Zope 3 programs on the same server, but we are not
there yet. Migration will be an application level affair, meaning that
if you have a custom Zope 2 application, you will have to make the
Sorry for this negative sounding answer. Zope 3 is super cool, but it
is a super cool development platform. Zope 2 was super cool too, and
Zope 3 is even super cooler. But moving to Zope 3 is at the moment a
lot of development work (you basically need to rewrite your
applictaion completely) and unless you plan on doing that anyway, you
should probably just stick with Zope 2 for the time being. :)
