Users can't transfer their WhatsApp chat history between platforms but have the option to export it as an email attachment.

Facebook-owned instant messaging platform WhatsApp will stop working on a number of devices, starting December 31. With over one billion users, WhatsApp is one of the most popular messaging apps in the world today.

As mentioned in the FAQ section of WhatsApp's official website, the messaging platform will end support for a number of devices running on Android, Windows, KaiOS, and iOS. According to the information provided on the page, the following devices will not be able to create new accounts, nor reverify existing accounts after February 21, 2020.

• Devices running Android v2.3.7 and older operating systems
• iPhones running iOS 8 and older versions
• All Windows Phone operating systems after December 31, 2019

Notably, WhatsApp might not be available in the Microsoft Store after July 1, 2019, the company mentioned on the page. However, the app will continue to provide support for the following devices:

• Android phones running OS 4.0.3+
