How to Update a SkyFactory 4 Server Safely

SkyFactory 4 updates are usually low-risk, but the resource world (RWG) dimension and per-island automation are the two things worth checking carefully. Backup first, update cleanly, verify before reopening.

Running SkyFactory 4? See the SkyFactory 4 pack page.

Start with a restore point

Back up the world before updating, including each active player's island.

Refresh the pack cleanly

  • Use the exact new SkyFactory 4 version.
  • Match Forge to the version the modpack specifies.
  • Avoid carrying over a hand-edited resource-world config blindly — check it still matches the new release's expectations.

Verify before you reopen the server

Confirm each active island's automation resumes and the resource world still generates correctly before inviting players back.
