My team is piloting a new workflow and wants to use a duplicate of their existing project. They want to retain a copy of the existing project as back up if they wish to revert to the old workflow (including all cards intact). Is there a way to do this? If I duplicate the board it appears to drop all dates/assignments etc. The duplicate tasks also appear searchable. Could I duplicate and archive somehow so the cards do not appear as duplicates via search? Or is there an export/import solution? Thanks in advance!
