How to migrate/transfer WeChat chat history from old iPhone to new iPhone

From time to time you got a new mobile phone and you want to migrate the chat history from the old to the new phone. In this case I use the build in function "Migrate Chat to Another Device" in WeChat to achieve this. 

1. First of all you have to make sure that the old phone and the new phone are in the same local wlan.
2. Log in to your WeChat on your old phone and tap Me -> Settings -> General -> Backup & Migrate Chats -> Migrate Chats to Another Device -> Migrate Entire Chat History
3. WeChat on the old device should show the following now:
   
   
   4. Then leave the old phone untouched and log in to your WeChat on your new phone, tap Discover -> Scan to scan the qrcode from the old phone. It takes some minutes to load the chat history via local wlan from the old phone to the new phone. Thats it. 😀
