The business problem
Applications relying on retired models like Claude 2.0 face service failure because requests to retired models will fail, causing downtime in production workflows.
How this topic solves it
Implementing a proactive model lifecycle audit and migration strategy to transition workloads from legacy or deprecated models to active, supported replacements.
- Navigate to the Usage page in the Claude Console to export API usage data.
- Review the CSV export to identify specific API keys and model identifiers currently in use.
- Cross-reference identified models against the official model deprecation documentation to confirm their lifecycle status.
- Update application code to point to the recommended replacement model.
- Conduct thorough testing of the application with the new model before the official retirement date.
The process of identifying and replacing legacy models to prevent service failure.

- Migration Logic → Deploy replacement → Production
Expected business outcome
Continuous service availability and alignment with supported, high-reliability model versions.
Limitations and checks
Testing applications with newer models may reveal behavioral differences; verify this by running parallel evaluations of output quality before full deployment.
