I had been using Whatsapp on my old phone. I would like to transfer the messages to the new one. I had disabled uploading to google drive as I consider this too insecure. On the new phone I installed whatsapp but no messages were there.
I remember being able to do this in the past as Whatsapp integration with google drive is a relatively new feature, how did it used to work, did it download the saved messages from the whatsapp server? Since they're still on my old phone I hope they're retrievable. I'm considering using Titanium Backup to make a copy. Would this work?
When I try to open whatsapp on my old phone, it said the number cannot be verified (because I took the SIM card out and put it in my new phone) but I can still see in the background all the old messages.
