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

[Laurence Rowe]

Perhaps you can just create a simple buildout.cfg for the version of
ZODB you need:

[buildout]
parts = scripts
versions = versions

[versions]
ZODB3 = 3.8.6

[scripts]
recipe = zc.recipe.egg
eggs = ZODB3
interpreter = py

Grab bootstrap.py from
http://svn.zope.org/*checkout*/zc.buildout/trunk/bootstrap/bootstrap.py
then run python bootstrap.py followed by bin/buildout. That should
give you bin/strip_versions which you can run.
