By clicking on the second icon (backup) you can also quickly backup your existing Whatsapp data to the iMyTrans program (we care about our customers' privacy and this data will be saved only in your local device, to which we do not have access). You can transfer your photos, videos, files, music and wallpaper.
It might take minutes to hours depending on the amount of WhatsApp data. Keep both devices connected to the computer during the transfer. Click on 'Transfer' in the right below corner, to begin the process. The program should detect and display the devices.
