We are upgrading pega 7.2.2 to 8.3.3 and we realized Care management framework requires pega customer service and sales automation frameworks as a prerequisite. It was not in 7.2.2.

Did anyone face a similar situation? Digital delivery of software contains only care management framework related jar file(pcm.jar). Can we ignore prerequisites and proceed with the only care management framework work and remove these layers(customer service and sales automation) in the application dependency stack.
