+## Migrating from Snap to package/binary
+
+Snap installation is deprecated. If you are migrating from Snap to a package or binary installation on the same host and were using BoltDB, ensure you move the BoltDB file and repositories directory and update the corresponding paths in `config.json` for `database.boltdb` and `tmp_path`. Also adjust file ownership for the service user (e.g., `semaphore`).
 Download a `*.tar.gz` for your platform from [Releases page](https://github.com/semaphoreui/semaphore/releases). Unpack the binary to the directory where your old Semaphore binary is located.
