Yes, you can move cards between projects by duplicating and then archiving them. Here's how:
Duplicate the Card:
Click the three dots in the top right corner of the card.
Select 'Duplicate card into another project'.
Archive the Original Card:
Click the three dots in the top right corner of the original card.
Select 'Archive'.
This process will create a copy of the card in the new project while keeping your workspace organised by archiving the original.
