+## Migration
+
+### From Overseerr
+
+Seerr is compatible with Overseerr's data format. To migrate your existing configuration:
+
+1. Stop the **Overseerr** add-on.
+2. Install and start the **Seerr** add-on once to initialize its config directory, then stop it.
+3. Copy the Overseerr config files to the Seerr config directory using the SSH & Web Terminal add-on or a similar tool:
+
+   ```bash
+   cp -r /homeassistant/addons_config/overseerr/. /addon_configs/db21ed7f_seerr/
+   ```
+
+   > **Note:** If you customised the `CONFIG_LOCATION` option in the Overseerr add-on, replace `/homeassistant/addons_config/overseerr` with the path you set.
+
+4. Start the **Seerr** add-on. Your existing settings, users, and requests will be preserved.

+### From Jellyseerr
+
+Seerr is compatible with Jellyseerr's data format. To migrate your existing configuration:
+
+1. Stop the **Jellyseerr** add-on.
+2. Install and start the **Seerr** add-on once to initialize its config directory, then stop it.
+3. Copy the Jellyseerr config files to the Seerr config directory using the SSH & Web Terminal add-on or a similar tool:
+
+   ```bash
+   cp -r /homeassistant/addons_config/jellyseerr/. /addon_configs/db21ed7f_seerr/
+   ```

+
+### From Ombi
+
+Ombi uses a different data format and there is no automated migration path to Seerr. You will need to configure Seerr from scratch:
+
+1. Note down your Ombi configuration (media servers, users, notification settings, etc.).
+2. Stop the **Ombi** add-on.
+3. Install and start the **Seerr** add-on.
+4. Use the Seerr web UI to reconnect your media server(s) and reconfigure your preferences.
