Settings β Data movement in the sidebar lets you move a space or a board out of the current organization. Moving something takes everything inside it along β a space brings all its boards and their issues; a board brings all its issues.
Moving spaces
Under Spaces, check the ones you want to move, or use the swap icon on a single row to move just that one. Tap Move spaces, choose the destination organization, and confirm.
Moving boards
Under Boards, boards are grouped by the space they currently belong to. Check the ones you want to move, or use the swap icon on a single row. Tap Move boards, choose the destination organization and the space within it, and confirm.
Who can do this
Moving spaces and boards requires the Move spaces and boards administrative permission. See Permissions management.
