Build for multiple speed grades

I have a design for speed grade C8. Now purchase would like to buy chips with speed grade C7. Will the binary that was build for speed grade C8 function properly in a chip with speed grade C7 ? ...

Thank you all for your replies!

I added speed grades C7 C6 and I7 as migration devices and using C8 as base device, and got the following warning:

Warning: Devices selected for migration have different speed grades -- frequency limits are checked only for current device, not all devices

Does this mean that timing analyses as only been done for C8 or is it only Fmax that apply for C8 ?
