[Zope] Error Migration Data.fs from Zope 2.10.4 to 2.13.8

[Frank Kauff]

Hi all,

I'm trying to update from Zope 2.10.4 to 2.13.8 and have problems to 
copy Data.fs. No matter whether I try to directly copy Data.fs or use 
repozo, both times zope gives me the error

ValueError: Non-zero version length. Versions aren't supported.

Searching the net, this seems to be a common problem. However, I 
couldn't find a solution for it. Is there a tool anywhere that can 
convert Data.fs from older to newer formats?

Thanks,
Frank
