Updating from Pega Customer Decision Hub for Communications
This content applies only to Pega Cloud environments
Starting from Pega Customer Decision Hub 8.6, the capabilities of Pega Customer Decision Hub for Communications (formerly known as Pega Marketing for Communications) merge with Pega Customer Decision Hub. To update from Pega Customer Decision Hub for Communications 8.5 or earlier to Pega Customer Decision Hub 8.7, in your application definition, you need to replace the communications application with Pega Customer Decision Hub application.
Your system might contain rules that are built on rules that are specific to the retired communications application. During the update, you must add the Pega Customer Decision Hub for Communications legacy component in order to add the retired rules to the Pega Customer Decision Hub application. The legacy component ensures that the updated system can resolve these rules correctly.
An example of a retired rule is the xCAR class rule NBAMCCustomerClass. This rule is not part of Pega Customer Decision Hub. New implementations of Pega Customer Decision Hub derive their xCAR class from industry-specific xCAR components or custom configurations.
