Elasticache redis upgrade required

Problem Description: AWS is requiring (and forcing if not done) the upgrade of Elasticache Redis to 5.0.6 version.

Proposed Solution: The instance "automation-hub-redis" in the AWS account insights-stage is still running Redis 5.0.5. The deadline for the upgrade is set on December 15, 2023, 21:59:59 (UTC).

In order to have a greater degree of control of the upgrade, we would like that you perform it via app-interface before this date. To minimise the impact in your service, please make sure that your instance is configured as AWS recommends [1].

Your instance AWS configuration can be modified in app-interface through the file data/services/insights/automation-hub/namespaces/stage-automation-hub-stage.yml.

Please make sure the following configuration values are correctly configured:

• number_cache_clusters is at least 2
• multiaz_enabled is set to true
• automatic_failover_enabled is set to true

before the moment of the upgrade.

In order to trigger the upgrade, you will need to:

• Set engine_version to 5.0.6
• Set apply_immediately to true

In case of doubt, you can use the app-interface Elasticache documentation [2]
