The upgrade process includes updating three components:

1. Upgrade the Redis Enterprise operator
2. Upgrade the Redis Enterprise cluster (REC)
3. Upgrade Redis Enterprise databases (REDB)

If you are using OpenShift, see [Upgrade Redis Enterprise with OpenShift CLI]({{<relref "/operate/kubernetes/7.8.4/upgrade/openshift-cli">}}) or [Upgrade Redis Enterprise with OpenShift OperatorHub]({{<relref "/operate/kubernetes/7.8.4/upgrade/upgrade-olm">}}).

For all other Kubernetes distributions, see [Upgrade Redis Enterprise for Kubernetes]({{<relref "/operate/kubernetes/7.8.4/upgrade/upgrade-redis-cluster" >}}).

Upgrade compatibility

When upgrading, both your Kubernetes version and Redis operator version need to be supported at all times.

{{<warning>}}If your current Kubernetes distribution is not [supported]({{<relref "/operate/kubernetes/7.8.4/reference/supported_k8s_distributions.md">}}), upgrade to a supported distribution before upgrading. {{</warning>}}

RHEL9-based image

As of version 7.8.2-6, Redis Enterprise images are based on Red Hat Enterprise Linux 9 (RHEL9). This means upgrades require:

• Cluster version of 7.4.2-2 or later.
• Database version 7.2 or later.
• RHEL9 compatible binaries for any modules you need.

For detailed steps, see the relevant upgrade page:

• [OpenShift CLI]({{<relref "/operate/kubernetes/7.8.4/upgrade/openshift-cli">}})
• [OpenShift OperatorHub]({{<relref "/operate/kubernetes/7.8.4/upgrade/upgrade-olm">}})
• [Kubernetes]({{<relref "/operate/kubernetes/7.8.4/upgrade/upgrade-redis-cluster" >}})
