A client wants to move their trello board from one organisation to their another organisation.  How is done?

Hi Gail,

Assuming they are on another Workspace - to move a board to a new Workspace you must be an admin of the board, and a member of the Workspace you are moving the board to. To actually move the board, you would open the board menu and under Settings select Workspace Name and select the Workspace from the drop down menu. You can find more details here. 

Hope this helps.
