You'd have to find the instance one-by-one. If you manage to get hold
of them, you can set their __class__ attribute to the new class:

>>> class A:
...   def doit(self):print "old"
... 
>>> a=A()
>>> class A:
...   def doit(self):print "new"
... 
>>> a.doit()
old
>>> a.__class__=A
>>> a.doit()
new
