Answer 1

1. Go to portal_purgepolicy and set the number to some number (I usually use '3' to keep at least some history).

2. Run the following script:

   from DateTime import DateTime
   from Products.CMFCore.utils import getToolByName
   from Products.CMFEditions.utilities import dereference
   
   
   policy = getToolByName(self.context, 'portal_purgepolicy')
   catalog = getToolByName(self.context, 'portal_catalog')
   
   for count, brain in enumerate(catalog()):
       obj = brain.getObject()
   
       # only purge old content
       if obj.created() < (DateTime() - 30):
           obj, history_id = dereference(obj)
           policy.beforeSaveHook(history_id, obj)
           print 'purged object ' + obj.absolute_url_path()
