[Zope] Re: Zope will not start after failed 2.8.1 upgrade

Well, fortunatly I had last nights backup of the Data.fs.  Restoring 
that allowed Zope to be reverted to 2.7.7 and restart.

So here is my question.

Normally I have been able to upgrade Zope, and if the upgrade had 
problems, revert to a prior version by simple redirecting the startup 
and python to the earlier version. Zope 2.8.1 was different. The 
upgrade, at least on the surface, appeared to alter something in the 
Data.fs, which prevented reversion to 2.7.7.

I would be very interested in any insights into why this is.  Was I 
experience a Zope issue or a Python 2.3.5 issue?  The logs have not 
provided me an insight expect that the Mapping module was missing 
after the revert, which I don't think was an accurate assessment of 
the problem.
