Is there a way to move a card from one board to another?
To move a card from one board to another, click on the card to see Card Details. Scroll down to Actions and click Move to.
Choose Another board. The menu will appear. By default, you see the boards which are currently open (the same you see in the left-side navigation panel). Click Load more to load the other boards. Choose the board and the list you want to move the card to.
You’ll see a system notification that the card was moved.
