Question How can you update the server to new versions?

[Fernal2010D]

I want to update my server to the new versions, in my case from 1.19 to 1.20 but I don't know how I can do it without losing everything.
Do you know how to do it?

Stop your server first, take a backup by copying the entire folder (or just the world and plugins if that's all you really care about), replace the .jar you're currently using with the one you want and start your server.
