Huawei has officially announced that a special press conference for HarmonyOS 6 will be held on October 22nd at 2:30 PM. The company promises that HarmonyOS 6 will be more visually appealing， user-friendly， intelligent， secure， and smooth.
It is widely rumored that the Huawei Mate 80 series， set to launch next month， will be the first devices to officially run HarmonyOS 6. The upcoming press conference is also expected to reveal the debut date of these new devices.
As the launch event approaches， Huawei has updated its official website with a comprehensive tutorial for preparing to upgrade to HarmonyOS 6. This guide specifically addresses the process of upgrading from HarmonyOS 4 and HarmonyOS 5， with a strong emphasis on data backup procedures， particularly for external storage devices.

This list includes popular series such as the Mate 30/20 series and the P40 series， indicating Huawei’s commitment to extending the lifespan and upgrade capabilities of its older flagship devices.
Industry insiders and bloggers have speculated that the inclusion of these older models in the backup list suggests they may indeed support the HarmonyOS 6 upgrade. However， official confirmation from Huawei is still pending， which will alleviate user concerns and provide clarity on device upgrade eligibility.
