does this error means something for you:

2000-08-31T14:06:05 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\014\021' Traceback (innermost last): File /home/sms/Zope_220/lib/python/ZODB/Connection.py, line 447, in setstate SystemError: Failed to import class MEM from module __main__

It means that the object can't be unpickled because the module that the objects class is defined in cannot be imported. Whatever product / python code defines the MEM class is probably installed in your old instance but not in your new instance... Hope this helps!
