Changed phones but kept phone number. How do I transfer WhatsApp chats to new phone?

[AC Question]

The standard way to transfer WhatsApp chat history from one phone to another is through Google Drive. However, in my case, the new phone has a new SIM card with a number that has been transferred from the old one and the old SIM card has been invalidated. As a result, I can't access my WhatsApp chats on the old phone any more and I can't back them up to Google Drive.

An additional complication is that the old phone cannot accept the new SIM card (mini vs. nano) so I can't temporarily move the phone number back to the old phone.

Any idea? Thank you.

Moved to the WhatsApp forum.

Please provide a link to 'the Whatsapp forum', to which you moved my question. Can't find it on my own.

Sorry, I thought it'd be clear from the redirect in the original forum, as well as the link for where the post is currently: http://forums.androidcentral.com/wh...fer-whatsapp-chats-new-phone.html#post5617144

Unless you have cleared your chats in the old phone, WhatsApp should have them on their database. If you install WhatsApp in the new device and log it in, it should recognise your phone number and open any existing chats...

Well, that's the problem---it doesn't!
A new idea: I might restore the number to my old phone using a nano-mini SIM card adapter, if I get one.

How did that go?
