Upgrade MSR Using Helm

Use this procedure to upgrade a Helm-managed MSR 4 deployment running on Kubernetes.

Before you start, review Semantic versioning to confirm that your intended upgrade path is supported.

Prerequisites

• Helm 3.x is installed.
• You have cluster-admin or equivalent RBAC permissions on the target cluster.
• kubectl is configured to point at the target cluster and namespace.
• For HA deployments, the external PostgreSQL and Redis/Valkey instances used by MSR are running and accessible. To upgrade these external components, refer to the PostgreSQL and Redis/Valkey documentation.
• For single-host Helm deployments, internal PostgreSQL and Redis/Valkey are managed by the Helm release and are upgraded as part of the same operation.

Procedures

Select the procedure that matches your upgrade path:

• Minor and major upgrade
• Patch upgrade

If you encounter issues during either upgrade path, refer to Troubleshooting.
