The water doesn't cycle, the filter media does. So your plan will only get you half way there. You need to transfer a good wad of the filter media across to the new filter when the fry go into the tank. This might trigger a mini-cycle in the main tank but it should be ok if you reduce feeding a little over the following week and are not heavily stocked.
After transfer monitor the water parameters carefully and be prepared to do frequent small water changes should there be any sign of ammonia or nitrite.
