A board "default_board" is already created and a plan / roadmap "Default_plan" is based upon the same board "default_board". It has stories planned on it.
Can I create another plan /roadmap based on the same "default_board" and use the same stories and can line them up for different dates. Does this activity will overwrite the stories on the board with respect to the timelines.
I believe the plan is just a view and adding up stories, tasks and filling up the details won't affect the board contents. Please correct me if I have a wrong understanding.
