You can promote a non-reusable workflow task to a reusable task. Reusable tasks must have unique names within the repository. When you promote a non-reusable task, the repository checks for naming conflicts. If a reusable task with the same name already exists, the repository appends a number to the reusable task name to make it unique. The repository applies the appended name to the checked-out version and to the latest checked-in version of the reusable task.
