Migrate AT content easily

Say you need to migrate a bunch of content types and you need to switch from an old type to a new type, the code below will do it quick and easily:

from Products.contentmigration.inplace import InplaceCMFItemMigrator

for each cabotpage in folder.objectValues():
   migrator = InplaceCMFItemMigrator(cabotpage)
   migrator.dst_portal_type = 'CabotProduct'    # change the content type
   migrator.migrate()
