Avorion Server Update & Version Mismatch: Backup Before SteamCMD

Avorion Guide • Updated Aug 22, 2026

Avorion Server Update and Version Mismatch

Avorion’s update path is safe when the galaxy is saved and stopped first. It is risky when SteamCMD updates files underneath a running server or when a beta build is downgraded without a backup.

Backup-first sequence

  1. Announce maintenance and run /save.
  2. Run /stop and wait for a clean exit.
  3. Back up the complete galaxy directory.
  4. Update app 565060 with the intended branch.
  5. Start, inspect the log, and test one client before reopening.

Do not mix these states

StateRisk
Client updated, server oldJoin rejection or incompatible content.
Server updated, client oldSame mismatch in the opposite direction.
Beta server downgraded to defaultGalaxy files may be incompatible or corrupted.
Server updated, mods oldStartup or in-game errors.
Keep the previous server build and galaxy backup until the first post-update session completes. “The process started” is not a migration test.
