Migrating devices - Power and Ground on I/Os?

--- Quote Start ---

When using device migration, I find that I/O pins on some devices are supposed to be power or ground on other devices. Is it okay to connect I/O pins to power or ground on my board?

It's better to use Quartus II device migration setting. It will take care of the power and ground pins for you. If you are using the IO pin and it is supposed to be power pins on another device migration package, you'll get the warning or error message while running the fitter.
