Before trying to deal with the problem you state, I'll make two possibly 
simplifying observations:

1. There should be no need to do any migration when upgrading Zope. The 
ZODB has not changed, and you may simply copy it over or upgrade Zope in 
place.

2. ZSyncer is the best magic for copying objects from one instance to 
another.

As for your stated problem: I think self may not be what you think it 
is, because if it really is 'testStuff' it should work like you expect. 
I can't say why without knowing more.
