Necesse Save Migration After an Update or Host Move
Necesse worlds should be treated as data that needs a verified migration path, not as a file to overwrite blindly. Old guides sometimes describe a special “1.0 migration” command or a fixed world conversion. Do not run an undocumented command against a valuable world. Use the current server package and a tested copy.
Safe migration sequence
- Record the current client/server build, world name, host, and active data directory.
- Stop the server cleanly and copy the complete active world/save directory.
- Keep the original copy read-only or off the live machine.
- Install or update the target server package from the official Necesse server page.
- Place a copy of the world where the target package expects it; do not guess a path if the current launcher or panel exposes another one.
- Start the target with the same basic world/port settings and watch the log.
- Join with one client, inspect settlement, inventory, progression, and a recent build, then make a new backup.
What to verify in the test copy
| Area | Check |
|---|---|
| World identity | The expected world opens and the seed/map state is recognizable. |
| Players | Characters, permissions, inventory, and spawn behavior are intact. |
| Settlements | Residents, housing, jobs, storage, and protection behave normally. |
| Progression | Boss, crafting, research, and quest state is present. |
| Multiplayer | A second client can join and save a harmless change. |
If the target fails
Stop it, preserve the logs, and return to the original copy. Check build compatibility and the active data path before trying a different change. Use backup and restore and server setup. A fresh-world test helps separate a package problem from a world-specific problem.
About old “1.0” articles
Version labels and world behavior change over time. The current official server page and announcement stream are the right places to establish what is shipped today; a search result describing an old conversion tool is not proof that the tool still exists.
