WhatsApp may be working on a feature that will allow you to migrate your chat history from Android to iOS, as reported by WABetaInfo through (Android Central).
The feature was first noticed in the latest beta version of WhatsApp 22.2.74 for iOS and seems to confirm WABetaInfo‘s earlier discovery in beta version 2.21.20.11 for Android. Both updates point towards a feature that will allow you to transfer your WhatsApp chats from Android to iOS using the Move to iOS app.
WABetaInfo also shared some screenshots showing what the feature might look like. Judging by the images, it looks like WhatsApp will ask for permission before starting the transfer process, then instruct you to keep the app open and your phone unlocked while your chats are migrated.
WhatsApp first let users migrate their chat history from iOS to Samsung phones in September, and later expanded the feature to support chat transfers from iOS to Google Pixels and other Android 12 devices. Letting users transfer their chats from Android to iOS would close an obvious loop, but it remains unclear which devices will support the rumor feature, as well as when (or if) it will be rolled out.
