Yes. Go to the downloads page for the Vision+ on dji.com and grab the " Phantom 2 Vision+ FC200 Firmware v1.2.5g" download. It will be a zip archive. Unzip it onto an SD card, insert the card into the camera, then power up your Phantom. The camera will update automatically. I'm not 100% sure of the camera LED sequence for the Vision+ while it's updating. For the straight Vision, the camera's LED flashes yellow, I believe, during the updating, then green again when it's done. The zip file will include a readme that will undoubtedly describe the lights and the process.
Once completed, power down, remove the card, check it in your PC to make sure the file was renamed as described in the readme. If not, just repeat the process. It might take a couple of attempts. But once done and confirmed, you should be good to go.
