It is simple to move one or more contacts from one address book to another.
The first way
Right-click a contact and select Move from the drop-down menu.
The second way
Select contacts you want to move, then click 
on the Action bar. The Move Contact form will appear, allowing you to select a destination address book where your moved contacts are stored.
The third way
Use the drag-and-drop function to move one or more contacts to a new address book.
The drag-and-drop function is done more easily in the VCards view.
Note
You can only move contacts of a personal or shared address book if you have the Edit permission. You cannot move contacts in the address book which you do not have the Edit permission or contacts in a public address book.
