I'm not understanding how to execute an inplace migration via upgrade steps. I want to rename a field and migrate it's contents from the old name to the new name. Running the steps through portal_setup does execute, however, the data stored in the field does not migrate as expected. Also, the tests are failing because the old object is getting created with the new schema. Any help would be appreciated. I can include the tests if that is helpful.
