+### Upgrade to Valkey cache
+
+As part of the TED infrastructure, Redis has previously been the default caching engine. We now recommend moving to [Valkey](https://aws.amazon.com/elasticache/what-is-valkey/), a community-driven alternative to Redis.
+
+For customers currently using Redis, [here is how to update to Valkey](/docs/guides/hosting-guardrails/updating-stacks/upgrade-to-valkey).
+
 ## Step 16: Configure Advanced - Foundation Parameters and Overrides
 
 The Foundation Parameters allow the TED stack to use SSM parameters defined in the TEF stack. You should only change these values if you did not use the default Resource Name Prefix (turbot) in the TEF stack.

+
+# Upgrade to Valkey Cache
+
+In this guide, you will:
+
+- Use the Turbot Enterprise Database provisioned product in service catalog to migrate from Redis to Valkey.
+- Monitor and troubleshoot the [Valkey](https://aws.amazon.com/elasticache/what-is-valkey/) upgrade process.
+
+[Turbot Guardrails Enterprise Database (TED)](/guardrails/docs/reference/glossary#turbot-guardrails-enterprise-database-ted) is an AWS Service Catalog product that automates the provisioning and management of the underlying database and caching infrastructure required for enterprise deployments of Turbot Guardrails.
+
+As part of its infrastructure, TED versions prior to 1.50 use Redis as the caching engine. This guide shows how to update a TED deployment using Redis to one using Valkey.
+
+The migration process described here will seamlessly provision new Valkey cache clusters and decommission the existing Redis instances, ensuring minimal disruption to your Guardrails environment.
+
+## Prerequisites
+
+- Access to the Guardrails AWS account with [Administrator Privileges](/guardrails/docs/enterprise/FAQ/admin-permissions).
+- Familiarity with AWS Console, Service Catalog and CloudFormation services.
+- TED version 1.50.x or higher.
+
+## Step 1: Pause Events
+
+[Pause the events](/guardrails/docs/guides/hosting-guardrails/troubleshooting/pause-events#pause-event-processing) to avoid any lost events. During this time, the respective workspace will still be available in `readonly` mode.
+
+>[!CAUTION]
+> AWS doesn't offer a direct path for migrating from Valkey back to Redis within ElastiCache. The supported migration path is from Redis to Valkey.
+
+Step 2: Select TED Version
+
+To begin the upgrade process, you’ll need to locate the TED provisioned product in AWS Service Catalog and initiate an update.
+
+Follow the initial steps outlined in the Updating TED guide to:
+- Access the AWS Service Catalog
+- Select the TED provisioned product
+- Initiate the Update action
+
+Once you’ve initiated the update, select the desired TED version under Product Versions.
+
+[!NOTE]
+Valkey is only available in TED version 1.50.x or higher.
+
+![Select TED Version](./service-catalog-select-ted-version.png)
+
+## Step 3: Update Parameters
+
+Under **cache**, choose `Valkey` as the ElastiCache Engine. Then select the desired version from the `Valkey Cache Version` dropdown.
+
+![Valkey Parameters Update](./service-catalog-ted-update-parameters.png)
+
+## Step 4: Update TED
+
+After verifying all parameters, scroll down and select **Update**. This initiates an update of several nested CloudFormation stacks, which you can monitor directly from the CloudFormation console.
+
+![Select Update](./service-catalog-ted-update-action.png)
+
+## Step 5: Review Deployment
+
+- [ ] The TED CloudFormation stack status should change to `UPDATE_COMPLETE` indicating the update completed successfully.
+
+![Update Progress ](./cfn-ted-update-progress.png)
+
+- [ ] The newly created Valkey caches will be available under `Valkey caches` in the AWS ElastiCache dashboard.
+
+![Verify Cache](./aws-valkey-cache-complete.png)
+
+## Step 6: Start Events
+
+Enable event processing. Refer [Enable the events](/guardrails/docs/guides/hosting-guardrails/troubleshooting/pause-events#enable-event-processing).
