What is the concept of Staging in Liferay?

The concept of Staging in Liferay primarily revolves around enabling users to preview changes before those changes go live. This is particularly important in content management systems where maintaining site integrity and ensuring that the user experience remains seamless is crucial.

Staging allows content creators and administrators to make modifications and prepare updates in a controlled environment without affecting the live site. This means that users can review and test changes, ensuring everything works as intended before publishing the content for public view. This process helps to minimize errors and maintain a polished presentation to end-users.

In contrast, managing long-term content archiving focuses on the retention and storage of older content rather than the pre-publishing process. Restricting access to content for external users deals with permissions and visibility, which is a different aspect of content management. Automating content updates across various channels refers to managing multi-channel content delivery, which is not related to the previewing and publishing workflow that Staging emphasizes.
