WhatsApp has rolled out a new feature that lets you transfer your chats without having to back them up on the cloud.
Previously, if you had to transfer your WhatsApp chat history you would need to go first upload it to the cloud. Android users are required to back up their chats to Google Drive, while iOS users upload it to iCloud. WhatsApp then lets you restore all your chats when you're setting up on a new or different device.
This feature is rolling out to WhatsApp users on Android and iOS. It however, only allows chat history between the same OS (operating system). This means that you can only transfer between Android devices and iOS devices. It doesn't allow cross-platform chat transfer yet. But it's still quite helpful as it doesn't require backing up your chats to the cloud although that is a safe option in case something happens to your phone.
