Make some reverse dieting as well. Don't eat from surplus suddenly to deficit.

Let say your bulking calorie now is 3000. Your maintenance is 2700cal. You want to cut at around 10%=2400.
Every week, decrease your calorie intake by 100 starting from 3000, 2900, 2800... until you reach 2400. This is to ensure your metabolism doesn't drop significantly and you can eat much food while cutting. Correct me if I'm wrong.
