Plone migration from 2.0.4 to 2.5 fails if ATCT 0.2-final with mxTidy was originally used

[agabriel]

Migrating (Plone Migration Tool) of Plone 2.0.4 to 2.5 fails if portal types are based on ATCT 0.2-final with mxTidy validator:

Error value: This object was originally created by a product that
            is no longer installed.  It cannot be updated.
            (<TidyHtmlWithCleanupValidator at broken>)

The reason for the problem is that modulealiases.py of ATCT 1.1.1-final does not consider the old validators library name. A solution is to add also a module mapping for validators.py

Adding of following lines in validators.py and modulealiases.py solve the problem:

   # in validators.py after line 24
   [..]
    __old_name__ = 'Products.ATContentTypes.Validators'
   [..]

and

   # in modulealiases.py after line 41
   [..]
   from Products.ATContentTypes.lib import validators
   [..]

Products, traceback, plone migration results:

Old site products:
Zope 2.7.5, Plone 2.0.4, ATCT 0.2-final

Current products:
Zope 2.9.4, Plone 2.5, ATCT 1.1.1

Sorry, but we do not support the migration from the highly experimental ATContentTypes releases prior to the ones included with Plone itself.

I had the same problem. It was due to objects (created with atct 0.2) with local schemas.

Fix :

• suppress local schemas in plone 2.0.5 instance and migrate after.

The script to suppres local schemas :

from Products.CMFCore.utils import getToolByName cat = getToolByName(portal, 'portal_catalog') brains = cat(portal_type='your_portal_type') for b in brains:

obj = b.getObject() if obj is None:

continue

if 'schema' in obj.dict:

del obj.schema
