Best practice for regular maintenance of a CyberPanel server

Hello, I’m fairly new to CyberPanel and wondering if you could do a guide on best practices for long-term server maintenance. Actually I have OS and CyberPanel system updates and I’m afraid to crash my server by applying them. Is it risky to do an apt get update and upgrade or not? I can’t find any information on this subject but I see a lot of posts mentioning problems after upgrades, it’s quite scary for a server that already has a few client sites on it.
