Final answer:
Typically, one does not need to delete the previous version of a Knowledge Article before updating; most content management systems allow direct editing with automatic version control. This provides a history of revisions for review and auditing purposes.
Step-by-step explanation:
When discussing updating a Knowledge Article, there is a standard process to follow which may differ depending on the content management system (CMS) being used. Typically, it is not necessary to delete the previous version first. Instead, the system may allow you to directly edit the existing article and save it, which either automatically creates a new version or overwrites the old one. This approach ensures that there is a trail of changes, which can be important for tracking revisions, especially in environments that require strict version control. Some CMS platforms maintain a version history, allowing reviewers and auditors to inspect changes over time.
