从一个堆栈中分离出 redis 集群

Question

I have a Redis Cluster which was created by using aws-cdk(python) . Basically i created this redis-cluster as a part of service-stack

my service-stack looks like below

s3 bucket
ecs cluster
lambda function
redis cluster

I want to seperate redis cluster from service-stack and want to place in another stack like redis-stack

Possible solution I need to remove redis cluster from service-stack and create an another stack called redis-stack and deploy my redis cluster

Issue My redis cluster is already deployed in PROD . I dont want to delete redis cluster

Goal without deleting existing redis cluster , I want to move the redis cluster from service-stack to redis-stack

Can anyone suggest a solution for this?

Generally it is possible to do it through import procedure as explained in Moving resources between stacks .

However, AWS::ElastiCache::CacheCluster does not support import procedure. Only some resources support it . Sadly, ElastiCache is not one of these resources.

So if you don't want to touch your prod cluster, for now you are stuck with what you have. Maybe in a near future support for importing, and subsequently moving AWS::ElastiCache::CacheCluster will be added to CloudFormation. Otherwise you would have to snapshot it, and recreated in a new stack.
