Hi @Whitney Kenny ,
Robocopy will simply copy the data, permissions, audit but not the actual "shares", for the shares you'll need to export the following registry key:
SYSTEM\CurrentControlSet\Services\LanmanServer\Shares and import it on the new server.
This is covered in the Microsoft documentation over here:
Saving and restoring existing Windows shares
