+## Upgrades
+
+If upgrading a subchart, such as PostgreSQL or MariaDB, or upgrading the `appVersion` in `./charts/nextcloud/Chart.yaml`, please never upgrade more than one major version at a time and please bump the helm chart `version` in `./charts/nextcloud/Chart.yaml` in line with semver. For example, if you bump the `appVersion` from `29.0.4` to `29.1.0`, you need to also bump the `version` from `5.3.0` to `5.4.0`.
+
+Additionally, when upgrading Nextcloud versions, upgrade to the latest minor version of the major version first, before upgrading to the next major version. Learn more about upgrading Nexcloud via the [upgrade docs](https://docs.nextcloud.com/server/latest/admin_manual/maintenance/upgrade.html#approaching-upgrades).
+
+If upgrading a subchart, please also provide documentation in the PR for how users can upgrade an external service locally.

 Check out the [official Nextcloud backup docs](https://docs.nextcloud.com/server/latest/admin_manual/maintenance/backup.html). For your files, if you're using persistent volumes, and you'd like to back up to s3 backed storage (such as minio), consider using [k8up](https://github.com/k8up-io/k8up) or [velero](https://github.com/vmware-tanzu/velero).
 
 # Upgrades
-Since this chart utilizes the [nextcloud/docker](https://github.com/nextcloud/docker) image, provided you are using persistent volumes, [upgrades of your Nextcloud server are handled automatically](https://github.com/nextcloud/docker#update-to-a-newer-version) from one version to the next, however, you can only upgrade one major version at a time. For example, if you want to upgrade from version `25` to `27`, you will have to upgrade from version `25` to `26`, then from `26` to `27`. Since our docker tag is set via the [`appVersion` in `Chart.yaml`](https://github.com/nextcloud/helm/blob/main/charts/nextcloud/Chart.yaml#L4), you'll need to make sure you gradually upgrade the helm chart if you have missed serveral app versions.

It's also good to first upgrade to the latest minor version of a major version before upgrading to the next major version.
