To duplicate project, follow these steps:
Use the Action button from the project detail or from the list of projects.
Choose the ‘Duplicate’ option.
Choose if you also want to copy all tasks from the previous project.
Click on 'Duplicate'
In project details, edit the duration, project category or assigned project managers if necessary.
When you duplicate a project with a budget, the budget is also copied over and automatically assigned to the project. You can make any changes in the budget by clicking on budget and saving new version as final.
When duplicating a project without a budget, the newly duplicated version won't have a budget either, except for the default "Not budgeted" item. After you create or assign a budget, the "Not budgeted" item is automatically removed.
