Kothar has found a way to copy Asana projects from one workspace to another, a feature not available from within Asana itself. You will need to create the target project in advance and the process requires some manual checking of project IDs but overall could be a great time saver. Essentially a PHP script that has been extended and made accessible via a front-end web interface, the process supports board-style projects and custom fields.
Asana's new "Boards" feature allows teams to manage even more types of work organized in even more ways. Teams can create boards to track work through multiple stages, like the classic kanban board with columns for “Ready to do”, “In progress”, and “Done.” Or, teams can get an overview of related lists, like blog post ideas, with columns for categories like “Thought leadership”, “Customer stories”, “Guest posts”, and “Company updates.” The board layout provides a simple and intuitive way for any team to manage projects small and large — right alongside all your other work in Asana.
