[ZODB-Dev] ZODB Upgrade Issues

[Mike MacDonald]

Hi People !
We are currently involved in the upgrade of a Zope 2.2.4 installation being 
used as a document server.
upgrading to 2.5.0   We have what appears to be an incompatibility between 
databases between the two versions.

While I'm sure there are more details required -- at this stage, is there 
any knowledge of a compatibility of this kind.   The main effect is that 
all of the documents appear to be corrupted, although native Zope documents 
and links appear to be fine.

Reinstalling a version of 2.2.4 and yields similar problems -- we don't 
seem to be able to revert.

I can supply error messages etc


I'd be very greatful for any help here -- we've worked hard to have Zope 
accepted in our org!
