How does Huawei transfer mobile phone data when changing mobile phones?

What I know about Huawei mobile phones is to transfer mobile phone data, use Huawei cloud services, use third-party software, use mobile phone cloning, and use WeChat chat records to migrate. Log in Huawei account on the old mobile phone, open "cloud backup", download and install some third-party software, such as "one-click telephone exchange" and "data migration". Huawei has its own telephone exchange tool, which can download and install "mobile phone clone" on new phones. If your important information is mainly WeChat chat records, you can use the chat records migration function that comes with WeChat.
