Migrating modded Minecraft from VPS to dedicated

Provision dedicated with equal or higher RAM than your peak JVM allocation. Install the same Java version and mod loader. Test modpack boot on the new host before DNS or IP cutover.

• Snapshot the VPS world and mod folders after a clean shutdown.
• Record server.properties, whitelist, and ops list.
• Schedule maintenance in Discord with a rollback plan.

Use rsync or scp between instances on the same Nexelya account for fast LAN-style transfers when possible. Verify checksums on world region files before starting the dedicated JVM.

Point players to the new IP, keep the VPS offline but intact for 48 hours as rollback. Monitor TPS and RAM on dedicated; adjust JVM flags if needed. Add Managed Ops backups on the new service before the next modpack update.
