   I think broken object MUST use ZODB.broken.Broken not OFS.Uninstalled.Broken

CW What makes it a bad persisten class?
   it`s not first-class persistent class.

xCW What makes you think it should?
load object 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.

JF Try setting _p_changed=1.
  object.__dict__ equals to {'_p_changed':1}

JF Or try accessing some other attribute.
  object.data

JF I'll look into this.  The first step will be to write a test for this.
JF The intent was definately that you would be able to get to a broken object's

not Test but for example ( if needed i try to spend time to write test )
