Kling AI Upgrade & Migration

Overview

This skill guides you through SDK version upgrades, API migrations, configuration changes, and handling breaking changes safely in Kling AI integrations.

Prerequisites

• Existing Kling AI integration
• Version control for rollback capability
• Test environment available

Instructions

Follow these steps for safe upgrades:

1. Review Changes: Check release notes for breaking changes
2. Update Dependencies: Upgrade SDK packages
3. Update Code: Adapt to API changes
4. Test Thoroughly: Validate all functionality
5. Deploy Gradually: Use canary or blue-green deployment

Version Compatibility Matrix

API Version | SDK Version | Status      | EOL Date
------------|-------------|-------------|------------
v1          | 1.x         | Current     | N/A
v1-beta     | 0.x         | Deprecated  | 2025-06-01

Model Versions:
- kling-v1     -> kling-v1 (stable)
- kling-v1.5   -> kling-v1.5 (stable)
- kling-pro    -> kling-pro (stable)

Breaking Changes by Version

v1.0.0 → v1.1.0

# No breaking changes
# New features:
# - Added camera_motion parameter
# - Added negative_prompt support

v0.x → v1.0 (Major)

# Breaking: Response structure changed

# Old (v0.x):
response = {
    "id": "job123",
    "state": "complete",  # Changed to "status"
    "result_url": "..."   # Changed to "video_url"
}

# New (v1.0):
response = {
    "job_id": "job123",   # "id" -> "job_id"
    "status": "completed", # "state" -> "status", "complete" -> "completed"
    "video_url": "..."     # "result_url" -> "video_url"
}

# Migration helper:
def migrate_response(old_response: dict) -> dict:
    """Convert v0.x response to v1.0 format."""
    return {
        "job_id": old_response.get("id"),
        "status": "completed" if old_response.get("state") == "complete" else old_response.get("state"),
        "video_url": old_response.get("result_url")
    }

Migration Scripts

Detect Current Version

import requests
import os

def detect_api_version() -> str:
    """Detect which API version is being used."""
    try:
        # Try v1 endpoint
        response = requests.get(
            "https://api.klingai.com/v1/account",
            headers={"Authorization": f"Bearer {os.environ['KLINGAI_API_KEY']}"}
        )
        if response.status_code == 200:
            return "v1"
    except:
        pass

    return "unknown"

print(f"Current API version: {detect_api_version()}")

Configuration Migration

import json
from pathlib import Path

def migrate_config_v0_to_v1(config_path: str) -> dict:
    """Migrate configuration from v0.x to v1.0 format."""

    with open(config_path) as f:
        old_config = json.load(f)

    new_config = {
        "version": "1.0",
        "api": {
            "base_url": old_config.get("base_url", "https://api.klingai.com/v1"),
            "timeout": old_config.get("timeout", 30),
            "max_retries": old_config.get("retries", 3)
        },
        "defaults": {
            "model": old_config.get("default_model", "kling-v1.5"),
            "duration": old_config.get("default_duration", 5),
            "aspect_ratio": old_config.get("aspect_ratio", "16:9"),
            "resolution": old_config.get("resolution", "1080p")
        },
        "rate_limiting": {
            "requests_per_minute": old_config.get("rpm_limit", 60),
            "max_concurrent": old_config.get("max_concurrent", 10)
        }
    }

    # Backup old config
    backup_path = config_path + ".v0.backup"
    Path(config_path).rename(backup_path)
    print(f"Backed up old config to {backup_path}")

    # Write new config
    with open(config_path, "w") as f:
        json.dump(new_config, f, indent=2)
    print(f"Wrote new config to {config_path}")

    return new_config

Code Migration

# Usage
upgrade = UpgradeProcedure()

try:
    upgrade.backup_file("config.json")
    upgrade.upgrade_dependency("klingai-sdk", "1.1.0")

    else:
        print("Upgrade successful!")

except Exception as e:
    print(f"Error during upgrade: {e}")
    upgrade.rollback()

Output

Successful execution produces:

• Updated SDK and dependencies
• Migrated configuration
• Updated code patterns
• Verified functionality
• Rollback capability if needed

Error Handling

Common errors and solutions:

1. Import Errors: Check package version compatibility
2. API Errors: Verify endpoint URLs updated
3. Response Parsing: Update response field names

Examples

See code examples above for complete, runnable implementations.
