@Nuno Castro You can continue to use UI Kit in your existing applications, but it is recommended to modernize to the latest UI architecture, which is Constellation, to better utilize the latest features. UI Kit 15.01 is the last version in the UI Kit series, and while it will still be supported, there won’t be any major enhancements in it. Therefore, for new applications, the recommendation is to use Constellation UI Architecture.

@Nuno CastroYes, when upgrading to Pega 24, you can choose to continue using UIKit by migrating to the latest version, such as UIKit 15. This allows you to maintain your existing UI framework while benefiting from updates and improvements. However, Pega has been focusing more on UI Constellation, which offers enhanced features, better performance, and improved support for modern user experiences. While keeping UIKit 15 is possible and can be a good short-term solution, it is generally recommended to consider transitioning to UI Constellation for long-term benefits and to stay aligned with Pega’s future developments. Before deciding, evaluate your project’s specific needs, the resources required for migration, and the advantages that UI Constellation might bring to ensure you make the best choice for your upgrade path
