Nexus 7 doesn’t have GSM facility. So that means installing Whatsapp on N7 shouldn’t be possible. But in my experience despite of it giving warning it installs straightforwardly. Here’s my exprience on how I migrated WhatsApp from my phone to Nexus 7.
1. Install Whatsapp on N7 from market or through APK file. But don’t open the app yet.
2. Create backup of existing Whatsapp messages:
If you don’t want to migrate existing messages then you can skip this step. Of course, there is no reason why you should skip, since its pretty easy. Just transfer the file: “msgstore.db.crypt” from phone to tablet, which resides at “/sdcard/WhatsApp/Databases/”. And keep the file in the same folder in N7. Create the folder database if it doesn’t exist.
