  "summary": "Upgrade Redis Enterprise operator, clusters, and databases on Kubernetes.",
  "content": "\nKeep your Redis Enterprise deployment up to date with the latest features, security patches, and bug fixes. The upgrade process involves updating three main components in sequence: the Redis Enterprise operator, Redis Enterprise clusters (REC), and Redis Enterprise databases (REDB).\n\n## Upgrade methods\n\nChoose the appropriate upgrade method for your deployment:\n\n- [Upgrade Redis Enterprise for Kubernetes](https://redis.io/docs/latest/operate/kubernetes/upgrade/upgrade-redis-cluster) - Standard upgrade process for most Kubernetes distributions\n- [Upgrade with OpenShift CLI](https://redis.io/docs/latest/operate/kubernetes/upgrade/openshift-cli) - OpenShift-specific upgrade using CLI tools\n- [Upgrade with OpenShift OperatorHub](https://redis.io/docs/latest/operate/kubernetes/upgrade/upgrade-olm) - Upgrade using OpenShift OperatorHub and OLM\n- [Upgrade with Helm](https://redis.io/docs/latest/operate/kubernetes/deployment/helm#upgrade-the-chart) - Helm-specific upgrade instructions for chart-based deployments\n\n## Upgrade process\n\nThe upgrade process includes updating three components in order:\n\n1. **Upgrade the Redis Enterprise operator** - Update the operator to the latest version\n2. **Upgrade the Redis Enterprise cluster (REC)** - Update cluster nodes and infrastructure\n3. **Upgrade Redis Enterprise databases (REDB)** - Update database versions and configurations\n\n## Upgrade compatibility\n\nWhen upgrading, both your Kubernetes version and Redis operator version need to be supported at all times.\n\nIf your current Kubernetes distribution is not [supported](https://redis.io/docs/latest/operate/kubernetes/reference/supported_k8s_distributions), upgrade to a supported distribution before upgrading. \n\n## RHEL9-based image\n\nAs of version 7.8.2-6, Redis Enterprise images are based on Red Hat Enterprise Linux 9 (RHEL9). This means upgrades require:\n\n- [Cluster version of 7.4.2-2 or later](https://redis.io/docs/latest/operate/kubernetes/7.4.6/upgrade/).\n- Database version 7.2 or later.\n- RHEL9 compatible binaries for any modules you need.\n\nFor detailed steps, see the relevant upgrade page:\n\n- [OpenShift CLI](https://redis.io/docs/latest/operate/kubernetes/upgrade/openshift-cli)\n- [OpenShift OperatorHub](https://redis.io/docs/latest/operate/kubernetes/upgrade/upgrade-olm)\n- [Kubernetes](https://redis.io/docs/latest/operate/kubernetes/upgrade/upgrade-redis-cluster)\n",
