    The big change is the switch from Unity to Gnome, which isn't really relevant for a server with no GUI. Other than that, it's just new versions of stuff.

    You'll have to upgrade to 18.04 or 20.04 at some point; 16.04 will reach end of life in April 2021. You don't need to upgrade until then if you don't need any of the new stuff, but after that you'll have to upgrade to keep getting security updates.

    Hello CatKiller,

    Thank you for your information. How to upgrade to 20.04 from my current running version? Is there any tutorial available?

    My recommendation is to wait at least one month after the release date to upgrade. So, around May-June would be a good idea.

    You can upgrade online with
    Code:
    sudo do-release-upgrade

    20.04 isn't released yet: it will be released in April 2020 - that's how the version numbers work. It's just that it will be released before 16.04 loses support, so it's an option to consider.

    You can't upgrade directly from 16.04 to 20.04, when it's released. You'd either need to go through 18.04 first or do a fresh install of 20.04 and restore your data from backups.

    To upgrade from 16.04 to 18.04 you just need to run sudo do-release-upgrade, as CelticWarrior says, and then the same to go from 18.04 to 20.04 when you're ready for that.

    The release notes for 18.04 are available here if you want more information about the changes.

    Thank you for your responses. If i upgrade using this command sudo do-release-upgrade, it won't affect my current running websites?

    It won't deliberately affect your running websites, but only you can do the necessary testing.
