If you want to switch from 6.0 to 7-0, you should first check to see if your device supports this new operating system at all. Anyway, I don't think you need to download the update from a separate page, but you need to check your phone's settings for these new update options for your phone. For example, my huawei p9 lite phone has an android 6.0, which I would like to upgrade to 7.0, because it is said to be possible, but unfortunately I can't find a new option to upgrade in the settings. I don't think it's in Hungarian yet, and if it does, it will go.
