旧应用程序在Windows应用商店中的IARC评级

Question

我读过年龄分级文档，上面写着，

"The first time you submit an app (or the first time you update an app that was published using the older age rating process), you will be prompted to take a multiple-choice questionnaire to determine your app’s age rating."

这是否意味着，我们必须为windows商店上已经存在的应用程序发布更新，才能提交IARC评级？或者我们可以在不发布更新的情况下提交评级？
