[ZODB-Dev] Migration to Zope 2.7.4 failed

[steffenl]

Hi,

curently I'm working on a Debian OS (testing). I've installed:
 Zope 2.7.4
 Plone2.0.5

I have an old Database that is running on Zope2.6.4 with Plone 1.0.4. After 
copying this old Data.fs File into the Folder of the new Instance and trying 
to migrate, I always recieve this error message:
