# Migration form PiAlert to NetAlertX
> [!WARNING]
> Follow this guide only after you you downloaded and started NetAlert X at least once after previously using the PiAlert image.
> [!TIP]
> In short: The application will auto-migrate the database, config, and all device information. A ticker message on top will be displayed until you update your docker mount points. Even so, it's always good to have a [backup strategy](https://github.com/jokob-sk/NetAlertX/blob/main/docs/BACKUPS.md) in place.
The migration should be pretty straightforward. The application installation folder in the docker container has changed from `/home/pi/pialert` to `/app`. That means the new mount points are:
| Old mount point | New mount point |
|----------------------|---------------|
| `/home/pi/pialert/config` | `/app/config` |
| `/home/pi/pialert/db` | `/app/db` |
If you were mounting files directly, please note the file names have changed:
| Old file name | New file name |
|----------------------|---------------|
| `pialert.conf` | `app.conf` |
| `pialert.db` | `app.db` |
> [!NOTE]
> The application uses symlinks linking the old db and config locations to the new ones, so data loss should not occur. [Backup strategies](https://github.com/jokob-sk/NetAlertX/blob/main/docs/BACKUPS.md) are still recommended to backup your setup.
In summary, docker file mount locations in your `docker-compose.yml` or docker run command have changed. Examples follow.
## Example 1: Mapping folders
### Old docker-compose.yml
```yaml
version: "3"
services:
pialert:
container_name: pialert
# use the below line if you want to test the latest dev image
# image: "jokobsk/netalertx-dev:latest"
image: "jokobsk/pialert:latest"
network_mode: "host"
restart: unless-stopped
volumes:
- local/path/config:/home/pi/pialert/config
- local/path/db:/home/pi/pialert/db
# (optional) useful for debugging if you have issues setting up the container
- local/path/logs:/home/pi/pialert/front/log
environment:
- TZ=Europe/Berlin
- PORT=20211
```
### New docker-compose.yml
```yaml
version: "3"
services:
netalertx: # ⚠ This has changed (🟡optional)
container_name: netalertx # ⚠ This has changed (🟡optional)
# use the below line if you want to test the latest dev image
# image: "jokobsk/netalertx-dev:latest"
image: "jokobsk/netalertx:latest" # ⚠ This has changed (🟡optional/🔺required in future)
network_mode: "host"
restart: unless-stopped
volumes:
- local/path/config:/app/config # ⚠ This has changed (🔺required)
- local/path/db:/app/db # ⚠ This has changed (🔺required)
# (optional) useful for debugging if you have issues setting up the container
- local/path/logs:/app/front/log # ⚠ This has changed (🟡optional)
environment:
- TZ=Europe/Berlin
- PORT=20211
```
## Example 2: Mapping files
> [!NOTE]
> The recommendation is to map folders as in Example 1, map files directly only when needed.
### Old docker-compose.yml
```yaml
version: "3"
services:
pialert:
container_name: pialert
# use the below line if you want to test the latest dev image
# image: "jokobsk/netalertx-dev:latest"
image: "jokobsk/pialert:latest"
network_mode: "host"
restart: unless-stopped
volumes:
- local/path/config/pialert.conf:/home/pi/pialert/config/pialert.conf
- local/path/db/pialert.db:/home/pi/pialert/db/pialert.db
# (optional) useful for debugging if you have issues setting up the container
- local/path/logs:/home/pi/pialert/front/log
environment:
- TZ=Europe/Berlin
- PORT=20211
```
### New docker-compose.yml
```yaml
version: "3"
services:
netalertx: # ⚠ This has changed (🟡optional)
container_name: netalertx # ⚠ This has changed (🟡optional)
# use the below line if you want to test the latest dev image
# image: "jokobsk/netalertx-dev:latest"
image: "jokobsk/netalertx:latest" # ⚠ This has changed (🟡optional/🔺required in future)
network_mode: "host"
restart: unless-stopped
volumes:
- local/path/config/app.conf:/app/config/app.conf # ⚠ This has changed (🔺required)
- local/path/db/app.db:/app/db/app.db # ⚠ This has changed (🔺required)
# (optional) useful for debugging if you have issues setting up the container
- local/path/logs:/app/front/log # ⚠ This has changed (🟡optional)
environment:
