You can also move other mailbox archives between vault stores, such as source archives that are not associated with archiving enabled mailboxes. You can move these archives to new destination archives, or to other existing archives that are not associated with archiving enabled mailboxes.

In cases like these, Move Archive moves the content from one archive to another. However, Enterprise Vault does not complete any shortcut processing because neither the source archive nor the destination archive is associated with an archiving enabled user.
