I tested again for WeChat migration and it was very simple and straightforward.
1. Go to "Me"
2. Go to "settings"
3. Go to "Chats"
4. Go to "Chat History Migration & Backup"
5. Go to "Migration"
6. Go to "Migrate to mobile/tablet WeChat"
7. Click "Select chats to migrate"
8. Click on "Select All" and click on "Start"
There will be a QR code on the screen. Once you log into another devide, use that device to scan this QR code and the transfer will start. It will transfer chats first and then chat history.
That's it!
