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 instantly 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 possibly can validate the goal Amazon Redshift Serverless warehouses with out impacting your manufacturing Amazon Redshift DC2 cluster. You can even use snapshot restore emigrate your Amazon Redshift DC2 workloads to completely different Areas or Availability Zones.

Stipulations emigrate utilizing a snapshot restore

1. Create an Amazon Redshift Serverless workgroup with a namespace. For extra data, 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 possibly can adhere to your group’s safety insurance policies.
3. Confirm that the Amazon Redshift Serverless namespace you’re making an attempt to revive to is connected to an Amazon Redshift Serverless workgroup.
4. To revive from a provisioned Amazon Redshift cluster to Amazon Redshift Serverless, the AWS Id and Entry Administration (IAM) person or function should have the next permissions: redshift-serverless:RestoreFromSnapshot, CreateNamespace, and CreateWorkgroup. For extra data, 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 technique.
