See How To Use DigitalOcean Snapshots to Automatically Backup your Droplets for more details on the snapshot process. On a DigitalOcean Droplet, one approach is to power down the system and take a snapshot (powering down ensures that the filesystem will be more consistent). Failing that, ensure that you have copies of user home directories, any custom configuration files, and data stored by services such as relational databases. The best way to accomplish this is to make a backup of your entire filesystem. Step 1 – Backing Up Your Systemīefore attempting a major upgrade on any system, you should make sure you won’t lose data if the upgrade goes awry. Before upgrading, consider reading the Bionic Beaver Release Notes and our article What’s New in Ubuntu 18.04. Keep in mind that libraries, languages, and system services may have changed substantially. You should never upgrade a production system without first testing all of your deployed software and services against the upgrade in a staging environment. Potential PitfallsĪlthough many systems can be upgraded in place without incident, it is often safer and more predictable to migrate to a major new release by installing the distribution from scratch, configuring services with careful testing along the way, and migrating application or user data as a separate step. This guide assumes that you have an Ubuntu 16.04 or later system configured with a sudo-enabled non-root user. You can follow our series on how to migrate to a new Linux server to learn how to migrate between servers. You may still need to review differences in software configuration when upgrading, but the core system will likely have greater stability. To avoid these problems, we recommend migrating to a fresh Ubuntu 18.04 server rather than upgrading in-place. Comprehensive backups and extensive testing are strongly advised. Warning: As with almost any upgrade between major releases of an operating system, this process carries an inherent risk of failure, data loss, or broken software configuration.
