# Migration guide 0.23.0 → 0.30.0

{% hint style="warning" %}
Migrating to `0.30.0` performs non-reversible database changes so downgrading to `<=0.23.0` is not possible afterwards. If you are running on an older ZenML version, please follow the [0.20.0 Migration Guide](/deploying-zenml/upgrade-zenml-server/migration-guide/migration-zero-twenty.md) first to prevent unexpected database migration failures.
{% endhint %}

The ZenML 0.30.0 release removed the `ml-pipelines-sdk` dependency in favor of natively storing pipeline runs and artifacts in the ZenML database. The corresponding database migration will happen automatically as soon as you run any `zenml ...` CLI command after installing the new ZenML version, e.g.:

```bash
pip install zenml==0.30.0
zenml version  # 0.30.0
```
