작은 규모의 Discourse 포럼을 S3로 성공적으로 이관해 보았지만, 이 더 큰 포럼을 이관하는 데 문제가 발생하고 있습니다. @marcozambi 님이 공유한 방법(Migrate_to_s3 task fails for placing too many requests - #2 by marcozambi)을 사용해야 할 것 같습니다. 가능하면 이 비공식적인 방법을 피하고 싶습니다. 
혹시 이전에 이런 문제를 겪어 보셨거나 해결책에 대한 아이디어가 있으신 분 계신가요? 에러 메시지는 아래와 같습니다:
root@server-app:/var/www/discourse# rails c
[1] pry(main)> SiteSetting.migrate_to_new_scheme = true
=> true
[2] pry(main)> Jobs::MigrateUploadScheme.new.execute(nil)
=> nil
[3] pry(main)> exit
root@server-app:/var/www/discourse# rake uploads:migrate_to_s3
