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_users_star_projects_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 MoveUsersStarProjectsService < BaseMoveRelationsService
    def execute(source_project, remove_remaining_elements: true)
      re
    
    def execute(source_project, remove_remaining_elements: true)
      return unless super

      user_stars = source_project.users_star_projects

      return unless user_stars.any?

      Project.transaction do
        user_stars.update_all(project_id: @project.id)

        @project.update(star_count: @project.starrers.with_state(:active).size)
        source_project.update(star_count: source_project.starrers.with_state(:active).size)

        success
      end
    end
