What is the effect of me Upgrading the CentOS 8 and is the Snapshot backup of the Server?

Hi @use142007,

From what I’m seeing, the command shouldn’t affect your DigitalOcean service. It’s always good to upgrade your distro whether it’s CentOS 8, Ubuntu 20.04, or something else entirely.

Regarding, Snapshots, they are on-demand disk images of DigitalOcean Droplets and volumes saved to your account. Use them to create new Droplets and volumes with the same contents. Basically, you can restore the whole droplet with them.

Hello there,

CentOS Linux 8 has reached End Of Life (EOL) on December 31st, 2021.

I would strongly recommend planning either migration to another OS like Debian or Ubuntu, or upgrading to CentOS Stream.

I also believe that CentOS Stream needs to be installed first, so I’m adding one more command:

sudo  dnf install centos-release-strea

I personally believe that the safest way to do this is to follow these steps here:

• Spin up a new Droplet with the desired OS
• Install the necessary services (webserver, sql server, etc.)
• After that using rsync for example copy over your files and migrate your databases
• Then test your website and server fully to make sure that everything is working as expected
• Finally, change your DNS to point to the new Droplet
