66 Notices will be applied.</para>
70 <title>Upgrading Using <quote>&os; Update</quote></title>
72 <para>The &man.freebsd-update.8; utility supports binary
73 upgrades of &arch.i386; and &arch.amd64; systems running
74 earlier FreeBSD releases. Systems running
75 <literal>7.[34]-RELEASE</literal>,
76 <literal>8.[1234]-RELEASE</literal>,
77 <literal>9.[012]-RELEASE</literal>,
78 <literal>10.0-RC[123]</literal> can upgrade as follows:</para>
80 <screen>&prompt.root; freebsd-update fetch
81 &prompt.root; freebsd-update install</screen>
83 <para>Now the &man.freebsd-update.8; utility can fetch bits
84 belonging to &release.current;. During this process
85 &man.freebsd-update.8; will ask for help in merging
86 configuration files.</para>
88 <screen>&prompt.root; freebsd-update upgrade -r 10.0-RELEASE</screen>
90 <para>Due to changes in the way that &os; is packaged on the
91 release media, two complications may arise in this process if
92 upgrading from FreeBSD 8.x or 9.x:</para>
96 <para>The &os;, which previously could appear in either
97 <filename>/boot/kernel</filename> or
98 <filename>/boot/GENERIC</filename>, now only appears as
99 <filename>/boot/kernel</filename>. As a result, any
100 kernel appearing in <filename>/boot/GENERIC</filename>
101 will be deleted. Please carefully read the output printed
102 by &man.freebsd-update.8; and confirm that an updated
103 kernel will be placed into
104 <filename>/boot/kernel</filename> before proceeding beyond
109 <para>The &os; source tree in <filename>/usr/src</filename>
110 (if present) will be deleted. (Normally the
111 &man.freebsd-update.8; utility will update a source tree,
112 but in this case the changes in release packaging result
113 in the &man.freebsd-update.8; utility not recognizing that
114 the source tree from the old release and the source tree
115 from the new release correspond to the same part of
120 <screen>&prompt.root; freebsd-update install</screen>
122 <para>The system must now be rebooted with the newly installed
123 kernel before the non-kernel components are updated.</para>
125 <screen>&prompt.root; shutdown -r now</screen>
127 <para>After rebooting, &man.freebsd-update.8; needs to be run
128 again to install the new userland components:</para>
130 <screen>&prompt.root; freebsd-update install</screen>
132 <para>At this point, users of systems being upgraded from &os;
133 9.2-RELEASE or earlier will be prompted by
134 &man.freebsd-update.8; to rebuild all third-party applications
135 (e.g., ports installed from the ports tree) due to updates in
136 system libraries.</para>
138 <para>After updating installed third-party applications (and
139 again, only if &man.freebsd-update.8; printed a message
140 indicating that this was necessary), run
141 &man.freebsd-update.8; again so that it can delete the old (no
142 longer used) system libraries:</para>
144 <screen>&prompt.root; freebsd-update install</screen>
146 <para>Finally, reboot into &release.current;</para>
148 <screen>&prompt.root; shutdown -r now</screen>
