If you are shifting from your old phone to a new phone, then it is not as difficult as before. But there are some things that sometimes remain in the old device. Especially text messages, which we sometimes forget to backup.
WhatsApp has the option to bring all your messages from the old phone to the new phone. WhatsApp is an instant messaging app and almost everyone uses it. Therefore it becomes necessary to transfer the chat present in the old device to the new device.
WhatsApp chats not only contain the necessary contacts and information but also include media attachments which are also needed in the new device. The easiest way to transfer WhatsApp chats is to backup them on Google Cloud or iCloud and after that, you can restore the chat on your new phone.
