1. you have to think about the resources that you used in the Apex device (logic cells and RAM) and see if the Cyclone III device will offer you at least the same amount;

2. you have to be careful about the needed I/O pins;

3. see if you find a speed grade suitable for your design;

4. make sure that the different power supplies are available in your new board

5. ask your Altera distributor about the price of the different Cyclone III models, he may have some special price on some of the part numbers for which he has a higher market

Anyway I suggest you to fit your Quartus II poject into the new device and check directly the performances before designing the new electrical diagram.
