Upgrade your Azure Cache for Redis instances to use Redis version 6 by 30 June 2023

Published date: September 30, 2022

Because Redis version 4 is no longer supported by the open source community, it will be retired from Azure Cache for Redis and you'll need to upgrade any cache instances that are running version 4 to version 6 by 30 June 2023. We'll continue to backport security fixes from recent versions to version 4 until that date.

Required action

To avoid an automatic update to your cache instances, upgrade your Azure Cache for Redis instances to Redis version 6 by 30 June 2023.
