I'm reviewing and organizing a project that, in the past, has had multiple devs and project managers working on it. There are three boards tied to it - two kanban and one scrum. Not all, but some issues are duplicated in the backlog of two different boards. I'm confused about where to start with organizing, removing duplicate tasks, etc. so the team can create a clear roadmap of work to be done.
Workflow management is typically kanban style for this project with a few sprints throughout the year. Do I start by moving issues on one board and delete the other board once migrated?
