Salut Jean-Marc,

I'm about to migrate a couple of documents from "documentish" to
folderish (FolderishProxyDocument)
CPS uses isinstance(ProxyFolderishDocument) in some places, so changing
to portal type to folderish is not enough.
instances must be changed too.
the current script does:
for brain in brains:
ob = brain.getObject()
if ob is None:
continue
if isinstance(ob, ProxyFolderishDocument):
continue
ob.__class__ = ProxyFolderishDocument
ob._p_changed = 1 # trigger persistence
ob.proxyChanged()
# + some workflow history stuff omitted here
anything more to think about ?
You may need to update the workflow related annotations on the object as
well and ensure it's compatible with the folferish workflow your objects
are gonna follow after this migration. I guess you will need to update
your workflow associations as well to specify a folderish workflow
instead of the former one.
Keep us posted about the result.

Yes, I did that too. The tricky issue was the __class__ change, it
didn't get persisted correctly in the beginning.
here is the entire script ...
cross-fingers ;-)
