In release 8.3, Pega Customer Service for Communications has modified the rules that invoke secured activities in Pega Platform. The query strings and parameters in the calls are registered so they cannot be tampered with by the end users.

If you have overridden any of these rules in your Pega Customer Service for Communications implementation layer, you need to update them to use the changed rules. Run the Pre-Upgrade Checker to identify which of these changed rules are overridden in your implementation layer. For information about the Pre-Upgrade Checker, see the Pega Customer Service for Communications Upgrade Guide on the Pega Customer Service for Communications product page.
