To migrate to AWS Signature Version 4, you need to update your code to sign requests using Signature Version 4.

* AWS no longer supports Signature Version 2. Signature Version 4 must be used for authentication.
* It's recommended to use an AWS SDK or CLI which will handle signing requests automatically using the latest signature version. Manually signing requests should only be done if an SDK or CLI is not being used.

```

* The signing process involves generating a string to sign and calculating the signature using HMAC-SHA256. Details are provided in the AWS documentation.
* Make sure any IAM credentials like access keys used by your application have the necessary permissions to access AWS services.
