[Bug]: Changing identifier in RDS Cluster and Cluster Instance (aws_rds_cluster & aws_rds_cluster_instance) forces recreate

[DemonICOLI]

Terraform Core Version

1.9

AWS Provider Version

5.0

Affected Resource(s)

• aws_rds_cluster
• aws_rds_cluster instance

Expected Behavior

Neither of those resources should be force recreated as this change can be done no issues on AWS Console... this also seem to affect normal instances at some point, but fix was not propagated to cluster, https://github.com/hashicorp/terraform-provider-aws/issues/507

Actual Behavior

Cluster and Cluster instances will have their identifiers updated without recreation

Relevant Error/Panic Output Snippet

No response

Terraform Configuration Files

resource "aws_rds_cluster" "postgresql" {
  cluster_identifier      = "aurora-cluster-demo" <--- CHANGE THIS
  engine                  = "aurora-postgresql"
  availability_zones      = ["us-west-2a", "us-west-2b", "us-west-2c"]
  database_name           = "mydb"
  master_username         = "foo"
  master_password         = "must_be_eight_characters"
  backup_retention_period = 5
  preferred_backup_window = "07:00-09:00"
}

I'm having the same issue. I simply want to change the identifier on the cluster and cluster instance and Terraform forces a recreate, which removes all data from the cluster. Is there any workaround?

Same issue here. It looks like workaround is to delete the resource from the state and re-import it...

Yes, I ended up removing the resources from the state, renaming the RDS cluster and cluster instance in the AWS console, and then re-importing them to the state. It works for now but it's a workaround.
