All ovens are different. Convection ovens usually call for lower temps and sometimes shorter cooking times. My convection oven needs to be set about 25 degrees lower than receipts call for. Cooking times very, depending on item being cooked. The user manual table provided with my oven worked for me most of the time. I live at a high altitude, so also have to adjust for that.
After you get used to your new oven, you will be very pleased with how your current baking receipts turn out.
