+    1. Stop Jellyseerr/Overseerr
+    2. Create a dataset for Seerr
+          If your apps normally store data under something like:
+          ```
+          /mnt/storage/<app-name>
+          ```
+          then create a dataset named:
+          ```
+          storage/seerr
+          ```
+          resulting in:
+          ```
+          /mnt/storage/seerr
+          ```
+    3. Copy ixVolume Data
+          Open System Settings → Shell, or SSH into your TrueNAS server as root and run :
+          ```bash
+          rsync -av /mnt/.ix-apps/app_mounts/jellyseerr/ /mnt/storage/seerr/
+          ```
+    4. Install Seerr and use the same Host Path storage that was created before (`/mnt/storage/seerr/config` in our example)
+    5. Start Seerr app
+    6. Delete Jellyseerr/Overseerr app

 If you are using a reverse proxy (such as SWAG or Nginx Proxy Manager), update your proxy configuration to point to the new container name `seerr`. The default port remains `5055`.
