Run the Copy projects process to copy data from existing projects to new projects. Select the project or the project component from which you want to copy data, and specify the data you want to copy. If you specify any data that have already been filled in for the new project, the existing data will not be overwritten.
You can copy entire projects, or parts of projects. This means you could reuse a previous subproject in a new project. Please bear in mind, however, that data can only copied between projects (or parts of projects) if they have the same type.
