Hi I have developed an add-on for plone 4.3 similar to https://github.com/collective/collective.examples.userdata/tree/0.4.1 and want to migrate an existing plone site from plone 4.3 to plone 5. The migration implies to modify the userdata add-on substantialy. The old add-on registers an utility for plone.app.user.userdata.userdataschema.IUserDataSchemaProvider that no longer exists on plone 5.
How should I accomplish the migration? Any examples?
Must I uninstall the utility before changing the zodb to plone 5?
Or create a mockup class for IUserDataSchemaProvider?
I'm facing this too.
Unless someone else knows how to work around it, I'll bang my head against it for awhile and let you know if I make any progress.
