seperate redis cluster from one stack

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?

Solution

  • 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.
