Dear John, I had problems with Plone4Artists Calendar, and the upgrade had a similar problem (PicklingError) at a similar point (migrating folders).
In http://plone.293351.n2.nabble.com/PicklingError-caused-by-p4a-calendar-interfaces-ICalendarSupport-when-migrating-from-3-3-5-to-4-0-7-tp6840461p6860779.html I posted a report on my strategy to upgrade Plone to 4.0.7, and removing Plone4Artists.Calendar. wildcard.fixpersistentutilities is your friend here. Hope it helps. On Sun, Oct 16, 2011 at 7:35 PM, John Reese <[email protected]> wrote: > Does anybody know how to get rid of references to old add-ons in Plone > 3.3.x?
