Introduction
------------

  This article describes how to upgrade using freebsd-update(8).

Upgrading from self compiled -STABLE or -RELEASE
------------------------------------------------

  freebsd-update(8) upgrades binary installations from original media
  only. If you try upgrading from non-binary installation you will get
  the following error:

    # freebsd-update upgrade -r 9.1-RELEASE

    Looking up update.FreeBSD.org mirrors... 1 mirrors found.
    Fetching public key from update1.FreeBSD.org... failed.
    No mirrors remaining, giving up.

  In order to updgrade from self compiled -STABLE or -RELEASE
  installations you need to make freebsd-update(8) think that you are
  running a supported binary release. To do that use:

    # env UNAME_r=9.1-RELEASE freebsd-update upgrade -r 9.1-RELEASE

  where 9.1-RELEASE is a release closest to the one you are
  running. If you want to see more information along the process use
  the option "-v debug".
