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

[Frank Kauff]

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 at aftol2 var]$ /opt/Zope-2.10/bin/python
Python 2.4.3 (#1, Sep 21 2011, 19:55:41)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-51)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import ZODB
 >>> ZODB.__version__
'3.7.1'
 >>>

[fkauff at aftol2 var]$ /opt/Zope-2.10/bin/python ../strip_versions.py 
Data.fs Data.fs.stripped
No handlers could be found for logger "ZODB.FileStorage"
Traceback (most recent call last):

   File "../strip_versions.py", line 107, in main
     ZODB.BaseStorage.copy(it, output_storage)
AttributeError: 'module' object has no attribute 'copy'


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

[fkauff at aftol2 ~]$ /opt/Zope-2.11/bin/python
Python 2.4.6 (#1, Oct  6 2011, 09:13:36)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-51)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> 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
