You should be able to backup the device to iTunes, then use iTunes to install the current version of iOS. If you're still running iOS 10 then you may well have 32-bit apps that won't work with iOS 12. You should review them before you commit. Rolling back is not an option. See How to see which apps won't work in ios 11 for details.
