On October 21, 2025, Huawei's official website posted an updated tutorial, guiding users on how to prepare for upgrading to the HarmonyOS system. The tutorial elaborates on the necessary preparations for transitioning from HarmonyOS 4 and HarmonyOS 5 to HarmonyOS 6, with a particular emphasis on the importance of backing up user data. It details methods for data backup using external storage devices and specifies the applicable Huawei products, including several models such as the HUAWEI Mate 30, HUAWEI P40, and HUAWEI Mate 40 Pro. Some users infer that these models, being older devices, will be eligible for the HarmonyOS 6 upgrade. However, the veracity of this inference awaits confirmation through Huawei's official announcement. Previously, Huawei's Executive Director, Richard Yu (Yu Chengdong), had disclosed that HarmonyOS 5.0 upgrades would be progressively rolled out to the vast number of Huawei phones currently in circulation.
