Legacy Model Lifecycle Management
Enterprises maintaining long-running AI applications that rely on specific model versions.
The business problem
Applications using retired models like Claude Instant 1.0 face service failure because requests to retired models will fail.
How this topic solves it
The solution involves auditing current API usage to identify legacy models and migrating workloads to active, supported models to maintain reliability.
- Access the Usage page in the Claude Console to retrieve API consumption data.
- Export the usage report as a CSV file to identify specific API keys and model versions in use.
- Cross-reference the identified models against the official deprecation documentation to determine retirement status.
- Update application code to point to the recommended active model replacement.
- Perform thorough testing with the new model to ensure task performance before the retirement date.
The process of identifying and replacing retired models.

Model identified as retired
Target replacement for migration
- Claude Console → Export → Audit Report
- Audit Report → Identify → Legacy Model
- Legacy Model → Migrate → Active Model
Expected business outcome
A stable, supported production environment that avoids service outages caused by model retirement.
Limitations and checks
Migrating to a newer model may introduce variations in output behavior; verify this by testing applications with newer models well before the retirement date.
