I am trying to understand more about design systems in Pega. Design system is more than a skin and it is right now shipped as an application within Pega. We have two design systems. 1) UI-Kit and 2) Cosmos. We are starting our development on 8.4 and have few questions on this.
Can we still continue to use UI-Kit before we get familiar with Cosmos. Is it a good option to change from UI-KIT to Cosmos later?
Does UI-Kit be deprecated in the coming releases?
I have seen one more application named Theme-Clarity. Is it a new design system?
Why do we have two design systems (Cosmos and UI-Kit). Is it support to existing upgrades?
