Answer 1

there is no need to use deprecated method in any case. in my case in need to update an existing object:

   AmazonS3Client s3Client =  (AmazonS3Client)AmazonS3ClientBuilder.standard()
                .withRegion(clientRegion)
                .withCredentials(new ProfileCredentialsProvider())
                .build();
  CopyObjectRequest copyRequest = new CopyObjectRequest(sourceBucketName, sourceKey, destinationBucketName, destinationKey)
        .withStorageClass(StorageClass.ReducedRedundancy);
        s3Client.copyObject(copyRequest);
