[Setup] zope upgrade on mac os x

[David Diskin]

My mac os x plone configuration has: plone 2.1.1,zope 2.7.8, python  
2.3.5.  Plone was installed using the Plone Mac OS X installer.  I  
have had problems moving over my Data.fs from my Plone 2.1.1 Zettai  
instance which has Zope 2.8.4 and it was suggested that my problem  
(see error at end of message) was due to the different zope versions   
I have these questions:

0. is the difference in Zope versions the actual cause of my problem?

1. Is it ok to upgrade to Zope 2.8.4 for the Mac Plone installation?   
I will just be using the Mac for development/test.

2. How can I do the upgrade - i.e. is there a how to somewhere on this?

3. Or, do I have to reinstall everything from source, which I have  
never done.

4.  Will the Mac OS X installer for plone 2.1.2 have the 2.8.x  
version of Zope?

Thanks very much.
David
