How to migrate Android device, including SD card? I have a Huawei Ascend G6, which uses a 32GB SD card to store most app data. I now bought a Huawei Y6 to migrate to and want to retain as much app data as I can. How would I go about to transfer my apps (data) to the new device?

The Y6 has Lollipop, so when booting the device, I was asked which apps to install. So I got all apps installed now. So how do I go about transferring configuration data? I assume I can't just put my SD card into the Y6 and be done with it?
You can try using Helium backup on the older phone in order to make copies of your apps and their settings. These can then be migrated to the new phone through the Helium backup interface. Alternatively, you could take an ADB backup of your old phone and restore it to your new phone. All this is on the assumption that you don't have root?
