1) Make a schedule, and stick to it
3) Update WordPress first, then plugins, and your theme last
4) Be prepared if something breaks
Even if you’ve been staying on top of your updates, you still might encounter some problems. It’s rare, and usually it’s not a big issue, but you want to be ready so you don’t experience any downtime. If your site breaks, immediately restore from your backup.
