That's an interesting question. The Motorola Migrate App only supports phones on Android 2.2 through Android 5.1, it will no longer work with Android 6 and above. However, one way for you to have your apps backed up is through Google Drive Backup. Just go to Settings > Backup and Reset > Toggle on Back up my account. You can also back up your Photos, just go to Photos App > Tap or Swipe down the screen until you see "backing up" > Once done, you should see "Backup Complete". Let me know how it goes.
