Upgrade Azure Cache for Redis instances to use Redis version 6
Hello, I want to upgrade current Azure Cache for Redis instances from version 4 to 6, following the below doc.
https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-how-to-upgrade
However, in my Advanced settings on the left side of the screen, I cannot see the blue banner of "This cache instance can be upgraded to Redis 6 with additional features...." which is mentioned in the doc, does it mean that my cache instance is not eligible to upgraded? Can I still upgrade using Azure CLI?

Also, do I need to upgrade the version of Redis Client library used in code ?
Thank you.
Regards,
Martin
