How do I upgrade my existing Debian installation?
I'm running an older version of Debian and would like to upgrade to the latest. How can I go about doing that?
You can upgrade your Debian installation by following the instructions in our guide.
Alternatively, you can spin up a second Linode with the latest version of your OS, configure it, and then transfer your files between them to complete the process. This second option can help you avoid downtime, but the new Linode must be in the same datacenter as your current Linode in order to swap IPs between them. If you create the second Linode in the same datacenter as the current, and then swap IP addresses between them, then you can avoid the need to wait for DNS propagation when switching your domain over to the new Linode.
