ModifyReplicationConfig

Modifies an existing AWS DMS Serverless replication configuration that you can use to start a replication. This command includes input validation and logic to check the state of any replication that uses this configuration. You can only modify a replication configuration before any replication that uses it has started. As soon as you have initially started a replication with a given configuiration, you can't modify that configuration, even if you stop it.

Other run statuses that allow you to run this command include FAILED and CREATED. A provisioning state that allows you to run this command is FAILED_PROVISION.
