If you mean simply trading one system for the other, then no, you cannot. The Nintendo DSi is worth about $150 while the DS Lite is worth about $110. You can, however, trade in the Nintendo DS Lite and cash for the Nintendo DSi. If you choose that method, you will need about $40 or so more to cover the cost. You can also choose to trade in your Nintendo DS Lite plus a game or two for the Nintendo DSi.
