In my company, we often do prototype development and later production development of a product. We use MantisBT not only for bug tracking, but for change management, open topic list and tasks, too. So we always have like 5-6 subprojects for 1 prototype development of a product.

When prototype development is finished and production development begins, we often need the subprojects from prototype development with all its' assigned users, special configuration, versions, categories and so on to be copied into new projects to be used for production development.

These subprojects are heavily customized (a lot of project specific configuration). Currently, it is not possible to do this with a few clicks. One has to add a new project and manually copy all configuration from the old to the new project one by one.

Please add a functionality, that allows to duplicate a project with all its configuration, users, roles, workflow ...
