I did a few from 6.6 to 7.3 and it was real easy.
The source I used was:
http://ftp.eu.openbsd.org/pub/OpenBSD/
Looks like this it the one that have the most files from the older version.
They have all the files from 2.0 and up. (;
Nice if you want to see how the system evolved over time. (;
Not saying it's the only one, but that's the best I found with all the
oldest one and it worked like a charm.
The only thing is that the file system change for the default type in
6.7 from ffs to ffs2.
The sysupgrade started in 6.6, so may be that's why my upgrades were
super easy.
But anything older then 6.7, I did the fresh installed because of the
file system change in 6.7
I didn't have any issue with softraid either for any systems that were
6.7 all the way to 7.3 and it was fairly quick.
At the end I also used the sysclean as well, BUT SETUP the
/etc/sysclean.ignore FIRST. Really that was took me more time to be sure
I did this right. But if your careful and know your systems, I see no
problem. If you use it without being careful, you CAN MESS YOURSELF real
bad!
Anything 6.6 and older I did fresh install to change the file system use
by default.
On softraid system upgrade from 6.7 to 7.3 easy as well. And you can see
the file syetem you use as well.
Softraid here:
sp1$ doas dumpfs /dev/rsd2a | head -1
magic 19540119 (FFS2) time Fri Sep 8 16:38:40 2023
So that's the only hickup may be that I can see.
One NONE Softraid system you see the same thing except this is
$ doas dumpfs /dev/rsd0a | head -1
magic 11954 (FFS1) time Thu Aug 24 16:29:48 2023
But on system like Octeon, the space from the /usr is just a bit to
small. :(
I didn't try top do it because of this.
Hope this help you and answer your question.

I've a problem. I need to upgrade OpenBSD from 6.5 to 7.3 on an APU2D. This
is a firewall.
The problem is that I cannot find older ISO of OpenBSD. Can someone point me
in the right direction?
If you are planning to go the supported route and upgrade from release to
release,
you have eight rounds of upgrading ahead.
If this is a firewall that does not do anything else, I would join a few of the
other posters here in recommending that you back up the tiny number of files
that could differ from a default install do a fresh reinstall, only editing
in the things you need from your old /etc/ such as (likely most of) pf.conf.

Actually I upgraded from 6.5 to 7.0 and I learned many new things. Wow...I
love OpenBSD.
Please tell us about your experience ! it's probably going to be rather
interesting.
