Amazon WorkSpaces now offers an API to quickly modify the streaming protocol on your existing WorkSpaces without requiring you to go through migrate WorkSpace process. This feature will allow you to retain the root volumes after you switch your WorkSpaces streaming protocol from PC-over-IP (PCoIP) to WorkSpaces Streaming Protocol (WSP) or vice-versa. End users of WorkSpaces can now easily take advantage of WSP features like Webcam and Smart Card support. WorkSpaces administrators will benefit from this feature because they will not have to manage custom images and bundles configured solely for the purpose of utilizing multiple streaming protocols supported by WorkSpaces.
