Redshift DC2 노드 타임 RA3 업그레이드 시 크레딧 문의드립니다.

Based on the available information, I cannot provide specific details about migration credits for upgrading from DC2 to RA3 node types in Amazon Redshift. The sources don't contain information about any credit programs, eligibility criteria, or application processes for DC2 to RA3 migrations.

What I can share is that AWS is phasing out DC2 nodes, with end-of-life scheduled for April 24, 2026. After May 15, 2025, you won't be able to create new DC2 clusters, resize existing ones, or add nodes to current DC2 clusters. AWS recommends upgrading to either Amazon Redshift RA3 nodes or Amazon Redshift Serverless.

RA3 nodes offer several advantages over DC2, including:

• Independent scaling of compute and storage
• Managed storage that automatically moves cold data to cheaper storage
• Data sharing capabilities
• Write operations for concurrency scaling
• Zero-ETL capabilities
• Multi-AZ capabilities

For specific information about migration credits, eligibility, and conditions for your account, I recommend contacting AWS Support or your AWS account representative directly as this information is not available in the provided sources.
