Upgrading 4.1.6 to 4.2.1

1

Hello Plone gods. I am trying to upgrade an instance from 4.1.6 to 4.2.1 and I get many errors. I was hoping if any of you could help me get through them.

Here is when I run the buildout:

Here is when I run bin/instance:

Any help is appreciated,

Thank you.

Obviously the module collective.xdv does not seem to be compatible.

Answer is to migrate your theming stuff to plone.app.theming...this xdv stuff is ancient and has no longer a life in Plone 4.
