Hi Jesus,

maybe you are not aware of it, but Zope 4 runs both on Python 2.7 and 

So, the recommended upgrade path would be something like this:
- update to the latest 2.13 version
- update to Zope 4 on Python 2
- update to Zope 4 on Python 3 (which makes ZODB conversion necessary)

I do not think there are fixed dates when support for old versions get 
dropped - ususally the Zope support is coupled to the Plone support - so 
if any supported Plone version needs a special Zope version, Zope gets 

You are definitely not on your own. There are Zope 4 sprints hosted by 
gocept (Halle/Saale, Germany), where you could take part, both 
contribute and learn about what to do. The next one is in May.

Also, if you cannot do the upgrade yourself, there are some companies 
out there which can do that for you.

There is quite some information out there about upgrade paths for Python 
software in general, but also especially for the Zope/Plone context 
(blog of gocept.net, starzel.de, https://zope.readthedocs.io/en/latest/

There are only so and so many Zope developers out there, so I would not 
bet on a long term maintenance of 2.13.
