Update&#8221;</a></h3>

<p>The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=freebsd-update&sektion=8&manpath=FreeBSD+8.2-RELEASE">
<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">freebsd-update</span>(8)</span></a> utility supports binary
&#09;upgrades of i386 and amd64 systems running &#09;earlier FreeBSD releases. Systems
running &#09;<tt class="LITERAL">7.[01234]-RELEASE</tt>, &#09;<tt
class="LITERAL">8.[012]-RELEASE</tt>, &#09;<tt class="LITERAL">8.3-BETA1</tt>, or
&#09;<tt class="LITERAL">8.3-RC[12]</tt> can upgrade as follows:</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> freebsd-update upgrade -r 8.3-RELEASE
</pre>

<p>During this process, FreeBSD Update may ask the user to &#09;help by merging some
configuration files or by confirming that &#09;the automatically performed merging was
done correctly.</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> freebsd-update install
</pre>

<p>The system must be rebooted with the newly installed &#09;kernel before
continuing.</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> shutdown -r now
</pre>

<p>After rebooting, <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=freebsd-update&sektion=8&manpath=FreeBSD+8.2-RELEASE">
<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">freebsd-update</span>(8)</span></a> needs to be run &#09;again to
install the new userland components:</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> freebsd-update install
</pre>

<p>At this point, users of systems being upgraded from &#09;FreeBSD 7.4-RELEASE or
earlier will be prompted by &#09;freebsd-update to rebuild all third-party applications
(e.g., &#09;ports installed from the ports tree) due to updates in system
&#09;libraries.</p>

<p>After updating installed third-party applications (and &#09;again, only if <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=freebsd-update&sektion=8&manpath=FreeBSD+8.2-RELEASE">
<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">freebsd-update</span>(8)</span></a> printed a message
&#09;indicating that this was necessary), run &#09;<a
href="http://www.FreeBSD.org/cgi/man.cgi?query=freebsd-update&sektion=8&manpath=FreeBSD+8.2-RELEASE">
<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">freebsd-update</span>(8)</span></a> again so that it can delete the
old (no &#09;longer used) system libraries:</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> freebsd-update install
</pre>

<p>Finally, reboot into 8.3-RELEASE</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> shutdown -r now
</pre>
