My problem is exactly the describe in this post. I want to move my whatsapp account from my old phone to a new one, but the SIM of the old phone is already expired (nonetheless, I currently can use my whatsapp in it). In my case what I want is to continue using that Whatsapp in my new phone. I dont care about the chat history or contacts (I already save them). So, I have read that in a rooted phone by accessing to the storage/Android/data and copying the com.whatsapp folder, and replacing it in the same directory of the new phone, the account can be moved and no verification number is needed. I have notice that even with a non rooted phone I can access to those folders copy them and replace them, as in the instruction, but in my case it did not work. Is there are differences in the content of, for instance com.whatsapp folder, when you access in rooted mode and non-rooted mode? If not, what I am doing wrong?

Many thanks in advance for any help you can provide me!!

My problem is exactly the one described in Migrate WhatsApp from phone (old expired number) to another one?.
