There should be an entry somewhere at raspberrypi.org. I'll explain:

First get installed version up to date:
  sudo apt-get update
  sudo apt-get upgrade
  sudo apt-get dist-upgrade (if any packages were skipped in upgrade)

Next - point repositories at 'stretch' vice 'jessie'
  sudo leafpad /etc/apt/sources.list
    and replace occurrances of 'jessie' with 'stretch'
  also edit files in /etc/apt/sources.list.d and replace
    jessie with stretch

Next - go for it:
  sudo apt-get update
  sudo apt-get upgrade
  sudo apt-get dist-upgrade
  sudo reboot

That should do it for you. It will take some time since there are a LOT
of packages and files involved.
