I have a Nokia 808. Whatsapp informed that their app will not be available on Symbian OS after 31-12-2017. Lumia 1020 has no memory card no any other phone directory, So how can i move WhatsApp backup to Lumia 1020.
Copy the data Whatsapp folder to this location Phone/Whatsapp in your Lumia 1020.
You can do this connecting your phone to a PC or compressing and sending the folder via Internet. You can use softwares like 8zip for compression. However connecting to a PC is an easy option.
