Server operations
- Dedicated server setup
- Compare managed server hosting
- Updating a server
- Existing world versus new world
- World backup and restore
- Move a local world to a server
- Crossplay configuration
- Server not showing
- Server requirements
- Server settings and configuration generator
Start with dedicated server setup, create a rollback copy with world backup and restore, then use the configuration generator to prepare a reviewed launch line. Troubleshooting separates Steam networking from PlayFab crossplay so the checks stay relevant to the selected backend.
