It might even be best to first upgrade to Zope 2.8 as an intermediate state. I would try it like this: 1. Upgrade to Zope 2.8.8 2. Upgrade to Plone 2.5 3. Upgrade to Zope 2.9.6 To me that sounds logical, but that is just me. :) I know a good mantra though that might help: Backups, backups, backups. ;) You may want to test different approaches and see which order of steps works best. -- Maurits van Rees | http://maurits.vanrees.org/ [NL] Work | http://zestsoftware.nl/ "Do not worry about your difficulties in computers, I can assure you mine are still greater." _______________________________________________ Setup mailing list [email protected] http://lists.plone.org/mailman/listinfo/setup
