Keep 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).
Upgrade methods
Choose the appropriate upgrade method for your deployment:
- Upgrade Redis Enterprise for Kubernetes - Standard upgrade process for most Kubernetes distributions
- Upgrade with OpenShift CLI - OpenShift-specific upgrade using CLI tools
- Upgrade with OpenShift OperatorHub - Upgrade using OpenShift OperatorHub and OLM
- Upgrade with Helm - Helm-specific upgrade instructions for chart-based deployments
Upgrade process
The upgrade process includes updating three components in order:
- Upgrade the Redis Enterprise operator - Update the operator to the latest version
- Upgrade the Redis Enterprise cluster (REC) - Update cluster nodes and infrastructure
- Upgrade Redis Enterprise databases (REDB) - Update database versions and configurations
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, upgrade to a supported distribution before upgrading.RHEL9-based image
Redis Enterprise images are now 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.
