# Amazon DMS Serverless limitations
<a name="CHAP_Serverless.Limitations"></a>

Amazon DMS Serverless has the following limitations:
+ You can only modify an Amazon DMS replication configuration that is in the `CREATED`, `STOPPED`, or `FAILED` states. For details about which settings you can change under which conditions, see [Modifying Amazon DMS serverless replications](CHAP_Serverless.Components.md#CHAP_Serverless.modify).
+ You can only delete an Amazon DMS replication configuration that is in the `STOPPED`, or `FAILED` states. 
+ Unlike replication instances, Amazon DMS Serverless replications do not have a public IP address for management tasks. You manage serverless replications using the console.
+ This release of Amazon DMS serverless does not support all the source and target endpoint types that Amazon DMS standard supports. For a list of supported engine types, see [Amazon DMS Serverless components](CHAP_Serverless.Components.md).
+ Serverless replications need to access dependencies by using VPC endpoints. You must use VPC endpoints to access the following endpoint types:
  + Amazon Amazon S3
  + Amazon Kinesis
  + Amazon Secrets Manager
  + Amazon DynamoDB
  + Amazon Redshift
  + Amazon OpenSearch Service

  For information about setting up VPC endpoints, see [Configuring VPC endpoints for Amazon DMS](CHAP_VPC_Endpoints.md).
+ Amazon DMS serverless does not support views.
+ Amazon DMS Serverless does not support SSL connections for DB2 endpoints.
+ Amazon DMS Serverless does not support setting custom CDC start points.
+ When a replication task is in deprovisioned state, the metadata related to the table and the replication statistics are lost.
