How thick?
How was it stored?
Do you want it straight/flat when you're done?

You'll have a difficult time flattening plywood once it's warped. You can force it to a different shape with one of several techniques, but warped ply made flat for cabinet sides (for example) will be very difficult. What would you like to do with this plywood?
