+# Upgrading out-of-date OpenBSD installs
+
+
+First of all, don't do how I do. 
+Upgrade your installs regularly. 
+OpenBSD makes it very easy.
+
+But, if you do happen to get behind...
+
+`sysupgrade` is very likely to fail.
+
+
+## What happens when you try to upgrade a very old install?
+
+
+Lots of 404 errors. 
+
+The `sysupgrade` utility tries to grab the next version of the OS from one of the many mirrors
+(the specific one your system will use is in `/etc/installurl`.)
+
+The default mirrors only keep the last 2 or 3 versions around,
+so when `sysupgrade` constructs the url and tries to hit it for downloads, it will fail.
+
+
+## Where to get old versions?
+
+
+There are a couple of mirrors that keep almost all the old versions around.
+
+<https://mirror.yandex.ru/pub/OpenBSD/> 
+has files going back to OpenBSD 2.x - they seem like 
+the most serious archivists, at least of the mirrors I looked at.
+
+<https://mirror.sjtu.edu.cn/OpenBSD/> 
+has files going back to 6.5 as of this writing (2022-11-11), 
+also not too shabby.
+
+Do a little `vi /etc/installurl` and change the link to one of the above, 
+depending on how delinquent you've been.
+
+That should allow you to do serial `sysupgrade` commands until you catch up.
+
+When you get close to the current version, 
+consider switching back to a closer mirror, 
+both for faster installs 
+and to be kind to the folks who just saved your bacon.
