Hi Paul,
When I upgraded my two instant on switches, I jumped straight to the latest version and was ok.
Before upgrading, I'd recommend saving your current config and then making backups of your "startup config" , and also your current "active firmware image". ( See attached screenshots).
After that, you can use the upload option, to update, the backup firmware image ( see attached screenshots).
The switch reboots in to the newly uploaded image.
If needed, you can revert back to your current level by choosing, the dual image configuration option & rebooting.
Good luck ππ»
