If your VPS is still on Ubuntu 22.04 LTS, it's time to put the upgrade on the calendar: standard support for 22.04 ends in April 2027. After that, free official security and maintenance updates stop, and staying put means vulnerabilities stop getting patched. There's still runway — which makes this the right moment to plan calmly rather than scramble at the deadline.

The Dates That Matter

  • Ubuntu 22.04 LTS: standard support through April 2027; security maintenance can then be extended via Ubuntu Pro ESM to 2032, and with the Legacy add-on as far as 2037.
  • Ubuntu 24.04 LTS: standard support through April 2029, with ESM running to 2034 — currently the safest landing spot.
  • Upgrade path: Ubuntu only supports moving one LTS at a time. Servers still on 20.04 must go to 22.04 first, then 24.04 — there is no single leap.

Three Viable Strategies

  • In-place upgrade (do-release-upgrade): least effort, fine for simple boxes running few services. The risk is third-party repositories, self-compiled components and stale config files breaking mid-upgrade.
  • Fresh install and migrate (recommended): spin up a new 24.04 instance, move your application and data across, verify everything, then switch DNS. Keep the old box for a few days as your rollback. This is the safest approach for production.
  • Buy ESM to extend: reasonable for legacy systems that genuinely can't move yet — but it's a buffer, not a destination.

Pre-Upgrade Checklist

  • Take a full backup or snapshot and confirm it actually restores. An unverified backup is not a backup.
  • Audit version compatibility: 24.04 ships newer major versions of PHP, Python, MySQL/PostgreSQL and OpenSSL. Older applications may simply refuse to run — test on a scratch instance first.
  • Clean up third-party repos and PPAs: incompatible sources are the single most common cause of failed upgrades. Disable them beforehand.
  • Book a maintenance window, and have rollback steps plus a backup SSH route ready so you don't get locked out mid-upgrade.

Use the Chance to Improve the Architecture

A release upgrade is a rare opportunity to do it right the second time. While you migrate, straighten out the shortcuts you took originally: right-size the instance to real load, containerize services for easier future moves, deploy closer to your users, and finally set up automated backups.

SharkCloud offers Ubuntu 24.04 LTS and other mainstream images, with fast provisioning for parallel migration and testing — so you can change OS generations without taking your service offline.
