Yes
There are several types of Nintendo DS systems ranging from the Nintendo DS, Nintendo DS Lite, Nintendo DSi, and Nintendo DSi XL. The newest version of the Nintendo DS is the Nintendo 3DS and Nintendo 3DS XL.
DSi Ware games and other downloadable content The Nintendo DSi Shop is specific to the region for which the system was manufactured. For example, a Japanese system can download DSi Ware games and other software only from the Nintendo DSi Shop for the Japanese region, regardless of where the system is being played. Nintendo DSi exclusive game cards Nintendo DSi game cards that are only compatible with Nintendo DSi and Nintendo DSi XL (and not Nintendo DS or Nintendo DS Lite) are region locked. This means game cards manufactured for the U.S. market would not work in a system made for another country. Nintendo DS / Nintendo DS Lite game cards Older Nintendo DS and DS Lite software is region-free, so you can play most of that software on a Nintendo DSi and Nintendo DSi XL from any region. It's possible, however, that future Nintendo DS software will incorporate region encoding. In these instances, these games would not work in a system made for another country.

Nintendo Dsi if you do not have alot of gba games because your prob trading in your ds lite if you have a gba or ds and ds lite i recommend dsi
yes you can use Nintendo ds games in a dsi
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.
