 # How to upgrade an existing Redis 4 cache to Redis 6
 
-> [!IMPORTANT]

 Azure Cache for Redis supports upgrading the version of your Azure Cache for Redis from Redis 4 to Redis 6. Upgrading is similar to regular monthly maintenance. Upgrading follows the same pattern as maintenance: First, the Redis version on the replica node is updated, followed by an update to the primary node. Your client application should treat the upgrade operation exactly like a planned maintenance event.
