+## Migrate to new labels without downtime
+
+1. Delete deployment with `--cascade=false`
+2. Delete the corresponding replicaset with `--cascade=false` too
+3. Add label to orphaned pods to match the new service selector
+4. Deploy the Helm Chart
+5. Wait for the newly created pods to get ready
+6. Delete orphaned pods using old selector labels
+
+
+## Example
+```bash
+kubectl delete deploy -l release=[RELEASE],app=[NAME] --cascade=false
+```
+```bash
+kubectl delete rs -l release=[RELEASE],app=[NAME] --cascade=false
+```
+```bash
+kubectl label pods -l release=[RELEASE],app=[NAME] \
+  app.kubernetes.io/instance=[RELEASE] \
+  app.kubernetes.io/name=[NAME]
+```
+```bash
+kubectl delete pods -l release=[RELEASE],app=[NAME]
+```

 ## Project Status
 
+As of [PR #75](https://github.com/t3n/helm-charts/pull/75) we dropped support for Helm v2 and switched to Helm Chart apiVersion v2. We also switched labels to [Recommended Labels](https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/). A detailed introduction on how to migrate without downtime can be found [here](LABEL.md)
+
 This project is still under active development, so you might run into [issues](https://github.com/t3n/helm-charts/issues). If you do, please don't be shy about letting us know, or better yet, contribute a fix or feature.
 We will also add more charts over time, so keep an eye on this repository.
