Ultimate 2026 Guide: Migrate Amazon Nova 1 to Nova 2 on Bedrock (Step-by-Step)
Migrate from Amazon Nova 1 to Amazon Nova 2 on Amazon Bedrock in 2026 to unlock faster reasoning, lower latency, and superior contextual awareness. AWS has officially deprecated Nova 1 support after Q4 2026 — acting now ensures uninterrupted AI operations and access to Nova 2’s breakthrough features like function calling, 128K context, and reduced hallucinations.
Step 1: Audit Your Current Converse API Integration
Before migrating, review all API calls using modelId: "amazon.nova-1". Identify endpoints, request volumes, and prompt templates. Use AWS Bedrock’s usage dashboard to flag legacy integrations. Confirm you’re using the Converse API — not the older InvokeModel endpoint — as Nova 2 requires it for full feature support.
Step 2: Update SDK and Dependencies
Upgrade your AWS SDK to version 2.200+ and ensure your Python, Node.js, or Java libraries support Nova 2’s new response schema. Replace amazon.nova-1 with amazon.nova-2 in all configuration files. Don’t forget to update IAM policies if new permissions are required for reasoning_steps or confidence_scores metadata.
Step 3: Refactor Prompt Templates for Nova 2’s Instruction-Following
Nova 2 responds better to structured, role-based prompts. Rewrite prompts to use clear directives like "You are an expert assistant" and avoid ambiguous phrasing. Test with AWS’s new prompt lab in the Bedrock console. Nova 2’s tokenization is optimized for natural language — avoid excessive punctuation or markdown.
Step 4: Test Latency and Reasoning Performance
Run A/B tests between Nova 1 and Nova 2 using real production prompts. Measure response time, token throughput, and accuracy using AWS CloudWatch metrics. Nova 2 shows up to 40% faster latency and 30% fewer hallucinations in benchmark tests. Track confidence_scores to validate output reliability before scaling.
Step 5: Deploy, Monitor, and Decommission
Deploy Nova 2 in staging with 10% traffic routing. Monitor error rates and user feedback via Amazon Bedrock’s new AI observability tools. Once stable, update your CI/CD pipeline to default to Nova 2. Schedule Nova 1 decommissioning before AWS ends support in Q4 2026.
