***Q. How do you perform Helm v2 release migration as a batch operation?***

A. You can perform batch migration of releases using a command as follows:

```console
$ kubectl get [configmap|secret] -n
\
 -l "OWNER=TILLER" | awk '{print $1}' | grep -v NAME | cut -d '.' -f1 | uniq | xargs -n1 helm 2to3 convert
```

An example of migrating releases which are stored as ConfigMaps in Tiller namespace `kube-system`:

```console
$ kubectl get configmap -n kube-system -l "OWNER=TILLER" \
 | awk '{print $1}' | grep -v NAME | cut -d '.' -f1 | uniq | xargs -n1 helm 2to3 convert
```
