Pega Foundation for Communications Upgrade from 7.2.2 to 8.2
We are upgrading a 7.2.2 environment with Pega Customer Service for Comms to a 8.2 Pega version. We need to upgrade the foundation for communications application. The upgrade guide for the foundation framework indicates that to upgrade to 8.2 we need 8.1 installed, 8.1 upgrade guide indicates we need 7.4 and so on. Is that correct, or we can go straight from a 7.21 Comms Foundation to a 8.2 version.
