Here's some code you come take and tailor to your use case. In the example below, I am retrieving a list of all security groups in the application, looping through them, and then deleting all the groups that have a prefix of ""RCM_"". Hopefully you have logical criteria you can use to implement to make this seamless and doable in one swoop. I would recommend dropping this code in an extender type business rule (found within the extensibility rules section) which will allow you to run the rule directly from the business rule page itself or via a DM job. Let me know if you have any questions.
