A new Minecraft version means new blocks, mobs, and mechanics for your server. But updating is not always smooth. Here is a step-by-step guide for server owners updating to the latest version.
Before You Update
1. Backup Everything
- Full world backup (all dimensions)
- Plugin/mod configurations
- Server properties and settings
- Player data
2. Check Plugin/Mod Compatibility
The biggest blocker for server updates is plugin and mod support.
Check these sources:
- SpigotMC plugin pages for update announcements
- Modrinth/CurseForge for mod updates
- Plugin developer discords
- GitHub issue trackers
Critical plugins to verify:
- Your economy plugin (Vault, EssentialsX)
- Permission plugin (LuckPerms)
- World protection (WorldGuard, GriefPrevention)
- Anti-cheat
- Any custom plugins
3. Test on a Separate Server
Never update production directly:
- Copy your server to a test environment
- Update the test server
- Install updated plugins
- Test for 24 to 48 hours
- Check for errors in logs
- Verify all key features work
Update Process
Paper/Purpur
- Download the new Paper/Purpur build for the target version
- Replace your server jar
- Update all plugins to compatible versions
- Start the server
- Paper handles world format upgrades automatically
Forge/Fabric
- Download the new Forge/Fabric installer for the target version
- Run the installer
- Update ALL mods to versions matching the new MC version
- One incompatible mod can crash the whole server
- Start and check crash reports if issues arise
Common Update Issues
Chunk Generation Border
Updated worlds get a visible border between old and new chunks. New terrain features only appear in newly generated chunks.
Solutions:
- Pre-generate new areas with Chunky
- Reset the nether/end (new features usually go here)
- Create a new resource world for gathering
- Keep the old world for builds, add a new exploration world
Plugin Errors
[ERROR] Could not load 'plugins/OldPlugin.jar'
The plugin is not compatible. Remove it and wait for an update, or find an alternative.
Data Pack Changes
Minecraft sometimes changes data pack formats. Custom data packs may break and need updating.
Timeline Strategy
- Week 1 to 2 after release: Wait. Plugins are not ready.
- Week 2 to 4: Major plugins release updates. Start testing.
- Month 2: Most plugins are stable. Safe to update.
- Month 3+: All plugins should be ready. Definitely update.
Rushing to update on day one means broken plugins and frustrated players. Patience pays off.
Communicating with Players
- Announce the update timeline on your Discord
- Explain why you are waiting (plugin compatibility)
- Let players know what new features they will get
- Set expectations for when the update will happen
