+# Migration

+## Helm v2 to v3
+
+- [ ] Backup Helm2 releases for rollback
+    - [ ] Get list of releases `helm tiller run -- helm list`
+    - [ ] For each release, backup Chart + values
+
+> Do we actually need backups???  
+> It seems that we could simply redeploy (rollback) with helm2 container  
+> Rollback would mean, cleaning up Helm v3 configs/secrets/deploys?  
+
+### Local cluster upgrade
+
+- [ ] Install Helm3
+    - Update `/sv/scripts/install_helm.sh` to use Helm version `v3.14.0`

+- [ ] Install [helm-2to3](https://github.com/helm/helm-2to3) plugin
+    - `helm plugin install https://github.com/helm/helm-2to3.git`
+- [ ] Migrate Helm2 to Helm3
+    - [ ] `helm 2to3 move config`
+    - [ ] `helm 2to3 convert sv-kube-proxy`
+    - [ ] `helm 2to3 convert sv-graphql`
+    - [ ] `helm 2to3 convert sv-geo`
+    - [ ] `helm 2to3 cleanup`
