So I guess it didn't work. :)
I'll look into this. The first step will be to write a test for this.
The intent was definately that you would be able to get to a broken object's
state.

Hello zope-dev!

I try to migrate my old database from zope 2.6.1.
I have Broken objects, but it is impossible to get its state in Zope 2.8.
In Zope 2.6 Broken objects have states, what i uses to migrate its.
I think this is because DB.classFactory is overrided to use
OFS.Uninstalled.BrokenClass, which is bad persistent class.
the __dict__ of all my Broken objects equals to {'_p_changed':None}.
my_object._p_mtime does not load it`s state.

object.__dict__ equals to {'_p_changed':1}
JF> Or try accessing some other attribute.
object.data
AttributeError('data') raise by OFS.Uninstalled.Broken.__getattr__

I think __setattr__ and __setstate__ overriden by ExtensionClass, but needfully
must be from Persistent. Or classFactory must return
ZODB.broken.{Persistent}Broken objects
