You could simply use WhatsApp’s own ‘Chat Settings’ which has an option ‘Email Chat’.
There are many ways to copy WhatsApp messages from Android to iPhone. You need to find other ways to transfer your WhatsApp chat history. That wouldn’t happen with your WhatsApp messages. If you secure your phonebook during the transition then your WhatsApp contacts are secured by default. You don’t want to lose your contacts, messages, emails that you may have on the phone and you certainly don’t wish to lose your WhatsApp messages. Either way, you need a few tools that would make this transition as convenient as possible. You could be switching from an Android to an iPhone or vice versa. But there are many who toggle from one popular platform to another. Many people stick to their iOS or Android and would rarely make a switch.
