Starting with FreeBSD 6.3, the freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems systems running earlier FreeBSD releases, release candidates, and betas. Users upgrading to FreeBSD 7.0 from older releases (in particular, older than 7.0-RC1) will need to download an updated version of freebsd-update(8) that supports upgrading to a new release.# fetch http://people.freebsd.org/~cperciva/freebsd-update-upgrade.tgz
Downloading and verifying the digital signature for the tarball (signed by the FreeBSD Security Officer's PGP key) is highly recommended.
# fetch http://people.freebsd.org/~cperciva/freebsd-update-upgrade.tgz.asc
# gpg --verify freebsd-update-upgrade.tgz.asc freebsd-update-upgrade.tgz
The new freebsd-update(8) can then be extracted and run as follows:
# tar -xf freebsd-update-upgrade.tgz
# sh freebsd-update.sh -f freebsd-update.conf -r 7.0-RELEASE upgrade
# sh freebsd-update.sh -f freebsd-update.conf install
The system must be rebooted with the newly installed kernel before continuing.
# shutdown -r now
Next, freebsd-update.sh needs to be run again to install the new userland components, after which all ports should be recompiled to link to new libraries:
# sh freebsd-update.sh -f freebsd-update.conf install
# portupgrade -faP
Finally, freebsd-update.sh needs to be run one last time to remove old system libraries, after which the system should be rebooted in order that the updated userland and ports will be running:
# sh freebsd-update.sh -f freebsd-update.conf install
# shutdown -r now
