A media company is using Amazon API Gateway to manage microservices that are implemented as AWS Lambda functions. The company's development team is planning to roll out another version of its API. To void affecting existing users when the new API is deployed, the company wants to give all users a 3-month eriod to migrate from the old API version to the new API version.
Which implementation strategy should the company use to achieve this goal?

A. Update the Lambda functions. Configure the API to use Lambda proxy integration.
B. Update the Lambda functions. Provide the API client with the new Lambda endpoints.
C. Use API Gateway to deploy a new stage that uses updated Lambda functions and provides users with a new URL.
D. Use API Gateway to redirect requests based on a request header to updated Lambda functions. Configure a 90-day expiration on the old API.
