In the past, switching to a new phone meant that you would lose most of your local data. Over time, it became easier to transfer your files, settings, and contacts, as long as you stayed in the same ecosystem. For example, if you get a new Android phone, your WhatsApp conversations and media will be restored automatically thanks to an online backup from Google Drive. However, in case you decide to get an iPhone, there is no official way to restore your conversations and media from your Android phone. WhatsApp is reportedly working to fix this warning, thanks to a native solution to automatically transfer your chat history between platforms.
It is no secret that WhatsApp is working to allow users to chat from multiple devices using the same number. Although it is not entirely clear how this feature will be implemented, it makes sense that WhatsApp also allows cross-platform backup. In fact, whether you use multiple devices simultaneously or simply switch from one to another, the structure for accessing and syncing your conversations between devices must be harmonized.
The feature is not yet available, but new leaks indicate that users will be able to migrate their chat history from iOS to Android and vice versa. Based on the screenshot above, it appears that the process will not be automated and might have to be activated manually to initiate the transfer.
It is essential to note that the feature is not yet implemented, so it could work differently when it officially comes out.
