# Migration from v1 to v2
## Before You Start
- Stop your Uptime Kuma and:
- Backup your `data` directory.
- Make sure you have a backup of your `data` directory again.
- Make sure you have a backup of your `data` directory again again.
- The migration process could take some time to complete, depending on the size of your database.
- You should be able to view the logs of the migration process in the console.
- Do not interrupt the migration process.
- FYI: My Uptime Kuma had 20 monitors and 90 days of data, and it took around 7 minutes to migrate.
- Beta version is not stable and may contain bugs, especially for the first beta release.
## Breaking Changes
- The `:duration` of these endpoints accepts `24`, `24h`, `30d`, `1y` only
- `<kuma-url>/api/badge/:monitorID/ping/:duration`
- `<kuma-url>/api/badge/:monitorID/uptime/:duration`
- Dropped support for legacy browsers
- The deprecated [backup](https://github.com/louislam/uptime-kuma/pull/3892) and [CachableLookup](https://github.com/louislam/uptime-kuma/issues/3762) features are completely removed now
- Default retires for **NEW**ly created monitors are now `0` instead of `1` to prevent users being confused
- `Email (SMTP)` switched templating for subjects/bodys from a custom-regex to [LiquidJS](https://liquidjs.com/).
LiquidJS **does discriminate between case-ness** of variables and **ignores all non-matching variables**.
These are the supported variables: `name`, `msg`, `status`, `heartbeatJSON`, `monitorJSON`, `hostnameOrUrl`
### Docker only
- Dropped support for Alpine base docker image (But you still can migrate to the v2)
- If your host are using Debian / Raspbian Buster, you should not upgrade. Due to the bug of libseccomp2, it will be running into a startup problem. Read more: https://github.com/louislam/uptime-kuma/issues/41#issuecomment-896164516
### Non Docker
- Dropped support for Node.js 14 and 16. The minimum supported version of Node.js is 18. Node.js 20 is recommended.

## Slim vs Full?
Slim version is a smaller image size, it is about ~300MB to ~400MB smaller than the full version.
Full version includes:
- Embedded MariaDB
- Embedded Chromium
- Embedded some fonts for Chromium
- Any big dependencies in the future may be included in the full version only too
If you don't need the above features, you can use the slim version.
## Rootless vs Non-Rootless?
Rootless tags are for users who want to run Uptime Kuma without root privileges, but some features may not work as expected.
Known issues:
- Docker monitor will not work without proper configure, as by default, it requires root privileges.
- If file permission is not set correctly, it may cause some issues.
- Unable to use embedded MariaDB, you will need to use external MariaDB.
## Migration Steps (Docker)
1. Stop your Uptime Kuma container.
```bash
docker stop uptime-kuma
```
2. Backup your `data` directory.
3. Change the image tag to `louislam/uptime-kuma:2-beta`.
```bash
docker run -d --restart=unless-stopped -p <YOUR_PORT>:3001 -v <YOUR_DIR OR VOLUME>:/app/data --name uptime-kuma louislam/uptime-kuma:2-beta
```
4. Check the logs to see the migration process.
```bash
docker logs -f uptime-kuma
```
## Migration Steps (Docker Compose)
1. Stop your Uptime Kuma stack.
```bash
docker compose down
```
2. Backup your `data` directory.
3. Change the image tag to `louislam/uptime-kuma:2-beta`.
```yaml
services:
uptime-kuma:
image: louislam/uptime-kuma:2-beta
....
```
4. Start your Uptime Kuma stack.
```bash
docker compose up -d
```
5. Check the logs to see the migration process.
```bash
docker compose logs -f
```
## Migration Steps (Non-Docker)
Beta is not available for non-docker yet.
<!--
1. Stop your Uptime Kuma.
```bash
pm2 stop uptime-kuma
```
2. Backup your `data` directory.
3. Check your Node.js version, the minimum supported version is 18. Node.js 20 is recommended.
```bash
node --version
```

## FAQ
### Can I migrate my existing SQLite database to MariaDB?
Cannot be done directly. You will need to export your data from SQLite and import it into MariaDB using 3rd party tools.
