 # Upgrading from v1 to v2
 
-This guide will help you migrate an existing codebase from the v1 Replicate Python SDK to v2. The v2 SDK is a complete rewrite generated in partnership with [Stainless](https://www.stainless.com/customers/replicate), the folks who help build and maintain SDKs for companies like OpenAI, Anthropic, and Cloudflare. The v2 SDK is largely autogenerated from Replicate's OpenAPI specification, providing better type safety, more consistent error handling, and improved async support. Check out the [v2 release notes](https://github.com/replicate/replicate-python-stainless/releases) for more details.
