I have two devices, the phone im currently using which is my primary WhatsApp device and an older device which hasn't connected to the internet for nearly 2 years and has the older version of WhatsApp in it with chats from 2 years ago. Is there any way I can merge these older chats into the WhatsApp of my current phone. I really want to switch on the internet in my older device but I'm too scared if the new chat would load resetting the older chats or something like that
