We are migrating from Pega 7.3.1 to Pega 8.2.1, in existing env (7.3.1) UIkit is pointing to UI-Kit-7:09-01-01 where as in Pega 8.2.1 the latest version of UIKit is UI-Kit-7:13-01-01.
If we are migrating to Pega 8.2.1, then we should point to latest UIKit version?

UI-kit is a showcase of the Pega Design System and is updated every release to stay in sync with the changes in the design system. As such Pega does not guarantee backward compatibility when upgrading from one ui-kit version to the other: after upgrading to ui-kit some of the colors, icons, styling or default behavior of your application might change. Upgrading to a new UI-Kit version is a development effort.
While we try to make it easy to upgrade to the latest version of ui-kit, some of the override CSS and sections from ui-kit that have been resaved into your application will need to be refactored and modified. The effort is similar to adopting and using some of the new feature provided in a Pega release. Before upgrading to a new version of ui-kit, please review all the available documentation, videos and release notes provided on the Pega community.
If you do not want to incur the development and testing cost of this ui-kit upgrade effort, you can keep using the same version of ui-kit. Each new release of the Pega Platform ships with all the version of the UI-Kit provided in previous releases.
