Making a change to your server — a RAM upgrade, a version switch, a region move, or a reinstall — naturally raises the question: will my world survive? Here's the short answer for each, plus the one habit that keeps you safe every time.

What happens to your data in each case

  • RAM/plan upgrade or downgrade: no data loss (just watch your disk usage on a downgrade).
  • Version/software change: your world is kept — files the Software page replaces are moved to a _previous folder (mind downgrade corruption when moving to an older version).
  • Region change / machine transfer: files are copied over; only the IP changes.
  • Reinstall Server: there's no Reinstall button in the client area — software is (re)installed from the Software page. A reinstall on the old panel can wipe — see the reinstall article; back up first.

The one habit that keeps you safe

  1. Before any of these changes, take a backup — Back up now on the Backups page, or download your world (and mods/plugins/configs) via Files or SFTP.
  2. Make the change.
  3. Verify the world loaded correctly before deleting your backup copy.

Tip: Always take a backup before upgrading, moving, or reinstalling, regardless of how safe the operation usually is. It costs a minute and saves your world.

Frequently asked questions

Will upgrading my RAM wipe my world? No. RAM/plan changes don't touch your data. Just keep an eye on disk space if you downgrade.

Does switching versions delete my world? No — it's kept (files the Software page replaces go to a _previous folder) — but be careful downgrading to an older version, which can corrupt newer world data.

Is reinstalling safe for my world? Not necessarily — reinstall can overwrite core files. Always back up first. See the reinstall article.
