You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: move_notification_settings_service.rb
    path of file: ./repos/gitlabhq/app/services/projects
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Projects
  class MoveNotifi
    
    def execute(source_project, remove_remaining_elements: true)
      return unless super

      Project.transaction do
        move_notification_settings
        remove_remaining_notification_settings if remove_remaining_elements

        success
      end
    end
