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.

Hi Laurence,

Please note that there are two errrors: The error "versions not supported"
comes  from Zope 2.13, but the other error appears when running from 2.10,
with ZODB 3.7:

[fkauff@aftol2 var]$ /opt/Zope-2.10/bin/python

I installed Zope 2.11 from old.zope.org, but it still comes with ZODB 3.7

[fkauff@aftol2 ~]$ /opt/Zope-2.11/bin/python
Python 2.4.6 (#1, Oct  6 2011, 09:13:36)

import ZODB
ZODB.__version__

'3.7.0b3'

ZODB.__path__

['/opt/Zope-2.11/lib/python/ZODB']


So the main question seems to be - which Zope version is old enough to be
able to read my Data.fs but recent enough to run the conversion script? Can
i get a 2.11 version with ZODB 3.8 from somewhere?

Thanks,
Frank

You probably need to run it using ZODB 3.8 (i.e. with your Zope 2.10
instance.)

I think that's what  did:

/opt/Zope-2.10/bin/python ../strip_versions.py Data.fs Data.fs.stripped

which gave the first error below

Or should I run it differently?

Zope 2.10 shipped with ZODB 3.7.x and only worked with Python 2.4.
Your error message is showing a problem in ZODB 3.10.3 for python 2.6.
I think you're running it in your Zope 2.13 buildout.

The strip_versions.py script needs to run with a ZODB released before
version support was removed. The script shipped with ZODB 3.8.x but I
expect it will also work with 3.7.x.
