My spouse just backup her iPhone 4S & restored using one of the latest version of iTunes
to an iPhone 6+ (on IOS 8.1.2).
Contacts, emails, photos & SMS messages are there. No Whatsapp applications so we
just installed from appstore & all Whatsapp groups got created.
But how do we get all the past Whatsapp threads of conversations (including images)
from the iPhone 4S to the 6+ ?
I recall there used to be a free service on one website that allows us to transfer
messages (think it's both whatsapp & SMS) from old phone to a new phone but
have lost the website's link
