Migrating devices - Power and Ground on I/Os?

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?

Yes you can connect I/Os to power and gnd. In addition to device migration this is a somewhat common practice for creating programmable ground or VCC pins to help minimize SSN by assigning as output driving GND connected to GND and output driving VCC connected to VCC on the board. It won't damage your I/O pins when they are defined as inputs in your design.
