⚠️ The school must be the same as created on the file server!

⚠️ The first command `net conf addshare` should be removed if you are migrating an existing share to the fileserver!

4. Run ```sophomorix-repair --all``` on the Linuxmuster-Server

## Migration

It is possible to outsource an existing share to a file server. To do this, install the file server as described above and then copy the files from ```/srv/samba/schools/default-school``` to the file server (for example, via rsync).

To set the permissions correctly, run ```sophomorix-repair --all``` after copying the files, and then run ```linuxmuster-fix-acls default-school``` on the file server to set the permissions recursively for all files and folders.

To do this:
- install the file server as described above, but without the command `net conf addshare` in the last script,
- copy the files from ```/srv/samba/schools/default-school``` to the file server (for example, via rsync),
- set the permissions correctly, run ```sophomorix-repair --all``` on the linuxmuster.net's server after copying the files,
- run ```linuxmuster-fix-acls default-school``` on the file server to set the permissions recursively for all files and folders.

A dedicated file server (file01) not only improves system architecture by separating concerns, but also provides significantly better performance in real-world SMB file operations.

This result reinforces the recommendation to avoid using domain controllers for file storage in performance-sensitive environments. A standalone file server improves throughput, reduces latency, and simplifies resource scaling.
