+The process is designed to be used in conjunction with the [postgres-cluster](https://github.com/alexlebens/helm-charts/tree/main/charts/postgres-cluster) chart. The cluster in this chart connects to the orignal cluster, peforms an upgrade, then backups to the objectStore endpoint. Afterwards the upgrade cluster is removed and the orignal cluster bootstraps from the upgrade's backup.
