# Retell AI Upgrade Migration
## Overview
Implementation patterns for Retell AI upgrade migration — voice agent and telephony platform.
## Prerequisites
- Completed `retellai-install-auth` setup
## Instructions
### Step 1: SDK Pattern
```typescript
import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });
const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);
```
## Output
- Retell AI integration for upgrade migration
## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| 401 Unauthorized | Invalid API key | Check RETELL_API_KEY |
| 429 Rate Limited | Too many requests | Implement backoff |
| 400 Bad Request | Invalid parameters | Check API documentation |
## Examples
### Upgrade an SDK through a compatibility canary
Pin the candidate SDK version in a branch and run the development agent suite
against synthetic create-call, retrieval, error, and webhook scenarios. Record
the old and new package versions and any changed request shapes, then deploy a
preview configuration before altering production dependencies. Keep the prior
lockfile and agent version available until the canary has met its error and
latency limits, so rollback does not require reconstructing the old runtime.
