To prevent data loss be sure you have an active and recent iCloud Backup.
If you get an error stating that there is not enough iCloud storage to back up your iPad, you can do one or more of the following:
1) Free up space on your iPad by moving your videos and photos to Google drive:
2) Get more iCloud Storage (99 cents per month for 50GB)
3) Remove old backups of other devices from your iCloud storage
