How to update VPS server


I was just thinking about about updating my VPS.
Before this was done by shared hosting provider.
Now, I have to think also how to update without downtime.

Any suggestions?
Is anyone else using VPS to host their own websites?
How do you update with minimal downtime?


What is it that you’re looking to update exactly, when you say “update your VPS”? Are you referring to package updates, or perhaps updating from one version of your distribution to the next?
