oops, B is correct, https://docs.aws.amazon.com/AmazonElastiCache/latest/mem-ug/Scaling.html#Scaling.Memcached.Vertically.API Scaling Memcached Vertically When you scale your Memcached cluster up or down, you must create a new cluster.

B is correct https://forums.aws.amazon.com/thread.jspa?threadID=194986 If you are using memcached engine, you can add additional nodes to your cluster to increase the total cache size. If you want to use bigger instance type, you will have to launch a new cache cluster and make your application to start using it.

A is correct for Memcached: https://docs.aws.amazon.com/AmazonElastiCache/latest/mem-ug/Scaling.html#Scaling.Memcached.Vertically.API B for Redis. https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Scaling.RedisStandalone.ScaleUp.html

What I read for MemCached, it seems B is right then To scale a Memcached cluster vertically (console) Create a new cluster with the new node type. For more information, see Creating a Memcached Cluster (Console). In your application, update the endpoints to the new cluster's endpoints. For more information, see Finding a Cluster's Endpoints (Console). Delete the old cluster. For more information, see Using the AWS Management Console.

Still believes A is correct https://docs.aws.amazon.com/AmazonElastiCache/latest/mem-ug/CacheNodes.NodeReplacement.html To manually replace a Memcached node Delete the node scheduled for replacement. For instructions, see Removing Nodes from a Cluster. Add a new node to the cluster. For instructions, see Adding Nodes to a Cluster. If you are not using Automatically Identify Nodes in your Memcached Cluster on this cluster, see your application and replace every instance of the old node's endpoint with the new node's endpoint.
