A server reaching its startup-complete message does not prove economy or land protection still works. An update can fail immediately or only after players use a specific feature. ## Record the current state For each target plugin, note its version, required dependencies and compatibility with the running Paper or Purpur build. Save a copy of its current JAR and data directory, plus any external database backups it relies on. Never assume a folder called `config` contains all its persistent data. ## Read release notes before uploading Look for Java requirements, breaking configuration changes, new dependencies, database migrations and special upgrade paths. Developers may require stepping through intermediate versions. Download releases from official project distribution pages, not random mirrors. A newer file is not necessarily compatible with older server builds. ## Make a staging copy Use an isolated test server with its own database credentials. Do not let a staging plugin migrate production tables. Copy a consistent world snapshot, install the proposed plugin version, and watch its full startup log. Retain the old JAR so you know precisely which artifact to restore if the test fails. ## Test the feature, not only plugin enablement | Plugin category | Acceptance test | | --- | --- | | Permissions | Normal member denied a staff-only command | | Economy | One purchase deducts and credits correctly | | Claims | Owner and guest retain correct access | | Punishments | Moderator can review prior sanctions | | Resource packs | Fresh client receives updated assets | | Cross-server data | Data remains consistent after reconnect | ## Update in a controlled maintenance window Announce downtime, take another production snapshot, stop the server, apply the exact tested versions and restart once. Inspect logs before reopening. If multiple plugins share a dependency, plan a coordinated upgrade for that group rather than repeatedly editing live files. ## What rollback really means Replacing a JAR may be insufficient after a plugin changes its database schema or saved data. Restore the matching configuration, data directory and database snapshot from the same recovery point. Test rollback on staging before depending on it. If a migration is irreversible, consult the project maintainer's documented recovery path. ## When not to update If a release is unrelated to a needed fix and introduces untested breaking changes, scheduling a later maintenance window can be reasonable. But don't ignore critical security or data-loss fixes. Prioritize severity, compatibility and the cost of delay. ## Frequently asked questions **Can I use `/reload`?** A full controlled restart is generally a more dependable test for complex plugins and dependencies. **Can I delete the old plugin folder?** Not without reviewing and backing up stored player data. **What if a plugin turns red?** Check the startup log and dependency messages using [our plugin troubleshooting guide](https://www.zcraftstudios.com/blog/minecraft-plugin-not-loading-fix). ## Related reading - [Staging Environment Guide](https://www.zcraftstudios.com/blog/minecraft-server-staging-environment-guide) - [How Often to Update a Minecraft Server](https://www.zcraftstudios.com/blog/minecraft-server-updates) - [Crash Report Analysis](https://www.zcraftstudios.com/blog/minecraft-server-crash-report-guide) ### Safely applying changes - [Paper Reload vs Restart Explained](https://www.zcraftstudios.com/blog/paper-reload-versus-restart-explained) ## Continue reading - [Velocity Modern Forwarding Setup and Security Checklist](https://www.zcraftstudios.com/blog/velocity-modern-forwarding-setup-checklist) - [Minecraft SMP Season Reset Checklist and Player Trust](https://www.zcraftstudios.com/blog/minecraft-server-season-reset-guide) - [Minecraft Staff Training Checklist: Permissions and Logs](https://www.zcraftstudios.com/blog/minecraft-server-staff-onboarding) - [Minecraft Join Spam and Bot Attacks: Defense Checklist](https://www.zcraftstudios.com/blog/minecraft-server-antibot-join-spam-defense) [ Previous guide Create Mod Server Setup: Loader, Modpack and Backups](https://www.zcraftstudios.com/blog/minecraft-create-mod-server-setup-checklist)[ Next guide Minecraft Inventory Missing After Update or Migration](https://www.zcraftstudios.com/blog/minecraft-server-join-but-inventory-gone)
