Deleting obsolete user behavior data collected for marketing activities
You can delete user behavior data that has not changed for a specified number of days. If you have Web or Dialog activities that use this data, do not run this script. The script can potentially delete data that is associated with active activities. In most cases, run the script to delete data for customers who are inactive. For example, to delete data for customers who have not been to the site for a year, set the -days value to 365.
