A methodical method to sizing validation, combining each pre-production testing and ongoing manufacturing monitoring, helps guarantee your Amazon Redshift Serverless configuration aligns along with your workload.

Improve to Amazon Redshift Serverless

To improve to Amazon Redshift Serverless, you need to use a snapshot restore to maneuver immediately from Amazon Redshift to Amazon Redshift Serverless, as proven within the following determine. A snapshot restore restores information and objects along with customers and their related permissions, configurations, and schema buildings. By utilizing snapshot restore for migration, you may validate the goal Amazon Redshift Serverless warehouses with out impacting your manufacturing Amazon Redshift DC2 cluster. You may also use snapshot restore emigrate your Amazon Redshift DC2 workloads to totally different Areas or Availability Zones.

Stipulations emigrate utilizing a snapshot restore

1. Create an Amazon Redshift Serverless workgroup with a namespace. For extra info, see creating workgroup with a namespace.
2. Amazon Redshift Serverless is encrypted by default. Amazon Redshift Serverless additionally helps altering the AWS KMS key for the namespace so you may adhere to your group’s safety insurance policies.
3. Confirm that the Amazon Redshift Serverless namespace you’re attempting to revive to is hooked up to an Amazon Redshift Serverless workgroup.
4. To revive from a provisioned Amazon Redshift cluster to Amazon Redshift Serverless, the AWS Identification and Entry Administration (IAM) consumer or position will need to have the next permissions: redshift-serverless:RestoreFromSnapshot, CreateNamespace, and CreateWorkgroup. For extra info, see Amazon Redshift Serverless restore.

Improve utilizing the console

Use the next steps within the AWS Administration Console for Amazon Redshift to improve your DC2 cluster to Amazon Redshift Serverless utilizing the snapshot restore methodology.

1. On the Redshift console, select Clusters within the navigation pane. Choose your cluster after which select Upkeep.
   
2. Select Create snapshot to create a guide snapshot of the present Amazon Redshift provisioned cluster.
   
3. Enter a snapshot identifier, choose the snapshot retention interval, after which select Create snapshot.
   
4. Choose the snapshot you wish to restore to Amazon Redshift Serverless from the listing after which select Restore snapshot and choose Restore to serverless namespace.
   
5. Below Choose namespace, choose your goal serverless namespace from the dropdown listing after which select Restore.
   
6. The restoration time will differ primarily based in your information quantity.
