• If you want to restore a previous version of IOS you are using on your ipad, you can restore it to a previous back up.
(KEEP IN MIND, when you are restoring your device to a PREVIOUS back up, whatever you have added, saved, downloaded…etc, to your device since the date of whatever backup you chose to restore to will be erased. You’ll only have whatever was on your device from the back you chose to restore. For example, if you want to restore your device from a back up that was saved 6 months ago, anything you have added to your device in the past 6 months will be deleted, and will downgrade to whatever version of IOS you had 6 months ago.)
if you want to restore it from a previous backup, you can do it on the device from a previous iCloud save, or by plugging it into the computer, and using your iTunes account to restore a previous backup.
if your issue is storage and you’re looking for more storage on your ipad you can always check to make sure that you’re using iCloud storage and iCloud Drive. If you go to settings, click on your Apple ID, click on iCloud, and you can make sure your, messages, notes and mail are turned on, check that photos are turned on and that optimizing storage is turned on for photos as well, then check that all other apps and features are turned on to use iCloud storage. If you need more you can upgrade the amount of iCloud storage you have as well.
you can also check your system storage to see what is taking up the most room on your device and if you’re not using it then delete it, and delete safari data/cookies/cache as well.
If you’re having trouble updating to the latest version of IOS, you can plug your device into your computer, then use iTunes to update your system.
