The first step would be to get your installation to run on Zope 2.13. There are 
already several changes in-between since Zope 2.10. Maybe you even have to 
upgrade to some minor versions in-between (2.11, 2.12) to be able to migrate 
your database and code to a recent Zope 2 version before trying to migrate to 
Zope 4+.

Re: [Zope] Developing 'products' for zope 4 and 5

Hi Kees,

in general the development for Zope 2 (latest version) and Zope 4 / 5 is not 
that much different. You have to read through the update notes. e.g. Chameleon 
is the new default template engine, some globals are no longer available, moved 
imports and so on.

As you correctly noted, the documentation is not completely up to date. There 
is just a lack of man power.

I suggest you try to follow the migration documentation ( 
https://zope.readthedocs.io/en/latest/migrations/zope4/index.html ).

If you encounter any problems, and you are able to solve them - report them 
back or update the documentation

If you cannot solve the problems yourself, don't hesitate to ask.

I recommend the https://community.plone.org/ forum - but try to ask some 
specialized questions - there is no "Zope 5 developer documentation" out there 
and just hidden from you.

You can also have a look at migrated products / packages.

If your application is a commercial one, you could hire someone to do the 
migration for you.

If the Python 3 thing is your problem, there is plenty of documentation out 
there, also from the Plone community:
https://docs.plone.org/manage/upgrading/version_specific_migration/upgrade_to_python3.html

By the way - these mailing lists are usually not used for those kind of 
questions, but almost only for announcements of new releases.

Best,
Jürgen

Betreff: [Zope] Developing 'products' for zope 4 and 5

Hi,
I am trying to catch up with the innovation that zope has undergone (I still 
have an instance running under zope 2.10.9).
Is there any more extensive documentation on how to develop ‘products’ for zope 
4 and 5. In the Zope Developer’s Guide the chapter on Zope products simply 
starts with the remark that the document is currently being reviewed.
best, cb
