| <para>To upgrade the jail to a new major or minor version, | |||||
| first upgrade the host system as described in | |||||
| <xref linkend="freebsdupdate-upgrade" />. Once the host has been | |||||
| upgraded and rebooted, the jail can then be upgraded. | |||||
| For example to upgrade from 12.0-RELEASE to 12.1-RELEASE, | |||||
| on the host run:</para> | |||||
| <screen>&prompt.root; <userinput>freebsd-update -b <replaceable>/here/is/the/jail</replaceable> --currently-running <replaceable>12.0-RELEASE</replaceable> -r <replaceable>12.1-RELEASE</replaceable> upgrade</userinput> | |||||

| &prompt.root; <userinput>freebsd-update -b <replaceable>/here/is/the/jail</replaceable> install</userinput></screen> | |||||
| <para>Then, if it was a major version upgrade, reinstall all | |||||
| installed packages and restart the jail again. This is | |||||
| required because the ABI version changes when upgrading | |||||
| between major versions of &os;. From the host:</para> | |||||
| <screen>&prompt.root; <userinput>pkg -j <replaceable>myjail</replaceable> upgrade -f</userinput> | |||||
