Duplicate a skill when you need variations of the same skill for different clients or document types. You can duplicate any custom skill. To modify a read-only Document skill (a Vantage built-in or a third-party skill), create a [derived skill](/vantage/documentation/skill-catalog/derived-skills/derived-skills) instead — the **Duplicate skill** button is unavailable for read-only Document skills. Skill Catalog with a read-only built-in skill selected, showing the Duplicate skill button disabled and a tooltip stating it is not available for read-only Document skills Availability of this feature depends on your role. For more information, see [Role-based access control](/vantage/documentation/tenant-admin/tenant-management/role-based-access). A duplicate is an exact copy of the original skill, including its description, demo documents, training documents, and all existing labeling. Select the skill from the list (click anywhere except the skill name), and then click **Duplicate skill** in the toolbar. Skill selected in the Skill Catalog with the Duplicate skill toolbar button highlighted ## After duplicating The copy appears in the Skill Catalog as ` (Copy)`.

To duplicate only the last published version, select the original skill and click **Discard changes** in the toolbar before duplicating.
