You should continue until you have scraped off the popcorn texture that is present over the whole ceiling, so exposing the drywall surface that is behind it. Following the completion of the task, you could wish to prime and paint the ceiling in order to give it a new appearance. This should be a piece of cake for you to do given that you have previously protected the space with plastic sheeting. Keep in mind that you should not remove the sheeting until the final topcoat has completely dried entirely. Also, make sure that any fixtures that you removed are replaced, and turn the power back on in the room.
Taking a step back, you can now appreciate the change! When the popcorn ceiling is removed, the space will immediately have a more contemporary and brighter atmosphere. Have fun at your new location!
