     34      Upgrading out-of-date OpenBSD installs
     35     </h1>

     40      First of all, don't do how I do. 
     41 Upgrade your installs regularly. 
     42 OpenBSD makes it very easy.
     43     </p>
     44     <p>
     45      But, if you do happen to get behind…
     46     </p>
     47     <p>
     48      <code>sysupgrade</code> is very likely to fail.
     49     </p>
     50     <h2>
     51      What happens when you try to upgrade a very old install?
     52     </h2>
     53     <p>
     54      Lots of 404 errors.
     55     </p>
     56     <p>
     57      The <code>sysupgrade</code> utility tries to grab the next version of
     58 the OS from one of the many mirrors (the specific one your system will
     59 use is in <code>/etc/installurl</code>.)
     60     </p>
     61     <p>
     62      The default mirrors only keep the last 2 or 3 versions around, so
     63 when <code>sysupgrade</code> constructs the url and tries to hit it for
     64 downloads, it will fail.
     65     </p>
     66     <h2>
     67      Where to get old versions?
     68     </h2>
     69     <p>
     70      There are a couple of mirrors that keep almost all the old versions
     71 around.
     72     </p>
     73     <p>
     74      <a href="https://mirror.yandex.ru/pub/OpenBSD/">https://mirror.yandex.ru/pub/OpenBSD/</a>
     75 has files going back to OpenBSD 2.x - they seem like the most serious
     76 archivists, at least of the mirrors I looked at.
     77     </p>
     78     <p>
     79      <a href="https://mirror.sjtu.edu.cn/OpenBSD/">https://mirror.sjtu.edu.cn/OpenBSD/</a>
     80 has files going back to 6.5 as of this writing (2022-11-11), also not
     81 too shabby.
     82     </p>
     83     <p>
     84      Do a little <code>vi /etc/installurl</code> and change the link to
     85 one of the above, depending on how delinquent you’ve been.
     86     </p>
     87     <p>
     88      That should allow you to do serial <code>sysupgrade</code> commands
     89 until you catch up.
     90     </p>
     91     <p>
     92      When you get close to the current version, consider switching back to
     93 a closer mirror, both for faster installs and to be kind to the folks
     94 who just saved your bacon.
