How to transfer Whatsapp to new phone 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.
There is two ways you can restore your whatsapp messages from old phone to your new phone.

1) Using Titanium Backup 


Backup Whatsapp app+data in old phone.
Copy the titanium backup of whatsapp to the new phone.
Restore data in new phone.


2) Copying Manually the messages


Copy the contents of SDCard/whatsapp/Databases from old phone to new phone
Paste the files in exactly the same location.
Verify using your number
