Hello,
I am trying to upgrade my existing Plone 3.3.2 ZODB to a Plone 4.0.1 on
Windows. I've tried upgrading using a buildout install (extends URL:
http://good-py.appspot.com/release/plone.app.registry/1.0b2?plone=4.0.1, the
default one would not work) and also using the official Plone-4.0.1.exe
installer.
Both Plone installations work fine on their own, but I get the same error
when trying to migrate the ZODB:
Ran upgrade step: Add new CMFEditions default modifiers.
Ran upgrade step: Upgrade MailHost.
Upgrade aborted. Error:
Traceback (most recent call last):

import of module zope.app.intid.interfaces failed
End of upgrade path, migration has finished
The upgrade path did NOT reach current version
Migration has failed
In case this is relevant, I had Singing&Dancing installed, which I had to
remove along with its persistent utilities )as described in
http://plone.org/documentation/kb/manually-removing-local-persistent-utilities)
or the Plone 4 would not even complete startup.
I tried searching both on Google and the Plone forums, but no lead so far.
Any help would be very much appreciated.
Best regards
Kevin
