Auroa backup cluster import to terraform


I have an Aurora cluster provisioned with terraform. In terms of disaster recovery its configured with multi AZ for automated failover. For data corruption event we plan todo Point In Time recovery by manually provisioning the cluster using the aws console in the event of data corruption to recover quickly.
After the newly restored cluster is provisioned I would like to manage the manually manage the provisioned cluster with Terraform.
What is the best way achieve this? Should I import the aws_rds_cluster and aws_rds_cluster_instance and tweak the configuration until I have no differences in the terraform plan or is there an alternative way achieve this?

Thanks guys.

Im essentially looking for advice or opinions on the subject.
