When you duplicate a project a copy of the project is created (with a new name) and the work is copied into the new project. Contrast this to the copy work option which copies work into the same project.
Note: This article refers to projects. Depending on your configuration, you may see alternate terminology used in your environment.
First select the what if control at the top of the planner.
Select the duplicate option.
Enter the name for the new project and check copy budgets and costs if you want to also copy the project's financial information.
Then select duplicate.
