There's no such thing as a tank that instantly cycles if you take a few days to move it long distance. While some beneficial bacteria still remains, there may not be enough to instantly support a full tank load like a properly cycled tank.
Your best bet is to dose ammonia and see how much the tank can actually handle. Some may be converted into nitrites while some may remain ammonia. Don't use nitrate levels as a sole indicator of a properly cycled tank.
