FreeBSD Update

The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.[012]-RELEASE, 7.3-BETA1, or 7.3-RC[12] can upgrade as follows:

# freebsd-update upgrade -r 7.3-RELEASE

During this process, FreeBSD Update may ask the user to help by merging some configuration files or by confirming that the automatically performed merging was done correctly.

# freebsd-update install

The system must be rebooted with the newly installed kernel before continuing.

# shutdown -r now

After rebooting, freebsd-update needs to be run again to install the new userland components, and the system needs to be rebooted again:

# freebsd-update install
# shutdown -r now

Users of earlier FreeBSD releases (FreeBSD 6.x) can also use freebsd-update to upgrade to FreeBSD 7.3, but will be prompted to rebuild all third-party applications (e.g., anything installed from the ports tree) after the second invocation of "freebsd-update install", in order to handle differences in the system libraries between FreeBSD 6.x and FreeBSD 7.x.
