### Step 1: Ensure Elasticsearch minimum requirements are met

MinIO requires a 5.x series version of Elasticsearch. This is the latest major release series. Elasticsearch provides version upgrade migration guidelines [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html).

### Step 2: Add Elasticsearch endpoint to MinIO

// parseJSON parses both the old and the new format for storing policy
// definitions.
//
// The on-disk format of policy definitions has changed (around early 12/2021)
// from policy.Policy to PolicyDoc. To avoid a migration, loading supports
// both the old and the new formats.
func (d *PolicyDoc) parseJSON(data []byte) error {
	json := jsoniter.ConfigCompatibleWithStandardLibrary
	var doc PolicyDoc
	err := json.Unmarshal(data, &doc)

* Fix GCE etcd scripts to pass in all required parameters for the etcd migration utility to correctly perform HA upgrades and downgrades ([#61960](https://github.com/kubernetes/kubernetes/pull/61960), [@jpbetz](https://github.com/jpbetz))

kube-aws, kubeadm etc) for specific advice.

1.6 encourages etcd3, and switching from etcd2 to etcd3 involves a full
migration of data between different storage engines.  You must stop the API
from writing to etcd during an etcd2 -> etcd3 migration.  HA installations cannot
be migrated at the current time using the official Kubernetes procedure.

 - Deprecated support for CSI migration of `Ceph RBD volumes`. Users who were relying on Kubernetes' ability
  to migrate to an out-of-tree storage driver should complete that migration before the support for it is removed. ([#118303](https://github.com/kubernetes/kubernetes/pull/118303), [@carlory](https://github.com/carlory))

- Introduced dynamic volume provisioning shim for CSI migration ([#73653](https://github.com/kubernetes/kubernetes/pull/73653), [@ddebroy](https://github.com/ddebroy))

- Remove check for CSI driver running on node for CSI migration ([#115772](https://github.com/kubernetes/kubernetes/pull/115772), [@sunnylovestiramisu](https://github.com/sunnylovestiramisu)) [SIG Apps and Storage]
