Amazon Redshift now supports changing node types within minutes with elastic resize
Amazon Redshift now supports elastic resize across node types. Customers can change node types within minutes and with one simple operation using elastic resize.
Elastic resize across node type automates the steps of taking a snapshot, creating a new cluster, deleting the old cluster, and renaming the new cluster into a simple, quick, and familiar operation. Elastic resize operation can be run at any time or can be scheduled to run at a future time. Customers can quickly upgrade their existing DS2 or DC2 node type-based cluster to the new RA3 node type with elastic resize.
Elastic resize across node types is supported with release version 1.0.10013 or later. Refer to the AWS Region Table for Amazon Redshift availability.
To learn more about using elastic resize with your Redshift cluster, see resizing clusters in the Amazon Redshift Cluster Management Guide.
