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.
The process is really easy, more easy than on Linux distros. I used
media installation images until I learned about sysupgrade, but I can't
run it due to cert.pem expired so I did proceed with media installation
from 6.5 to 7.0. At 7.0 I copied a valid cert.pem from a 7.3 install and
tried to run sysupgrade but it took very long time to get upgrades. I
don't know if this is due to my APU2D low resources (on a VM with 7.3 it
did very quickly) but sysupgrade stay there for several minutes before
starting something (that I can read).
I learned also about sysmerge and syspatch, I love this tools.
On 6.5 I installed wget with pkg_add and (obviously) running wget from
6.5 to 7.0 got seg fault. So I proceeded to remove all packages
installed with pkg_add. Here I learned new things about tool pkg_info.
So I reinstalled needed packages with pkg_add. This process is really
easy and clean.
I learned about a new tool called sysclean but I have not yet tried it.
Plus before every upgrade, I read notes from
https://www.openbsd.org/faq/upgradeXX.html I got good information about
what's updated and what changed for critical services like pf.conf
syntax changes. This helped me to reduce errors during upgrade.
During the upgrade process from 6.5 to 7.3 I expected a big changes in
the system but this is not the case. I love this, OpenBSD (through
upgrades) remains modern with new packages (including feautures) and
removing unsupported/obsolete software without modifing the core system
deeply. The best it does not change to much from 6.5 to 7.0 and this is
very good because it maintans a compatibility with scripts and software
used in older release (except is some case but it is rare in my usage
case). This is not the case of Linux like RHEL upgrades from one major
release to another one (I call that a big bang upgrade) where you need
to re-deploy all due to incompatibility. Probably the best linux distro
that is similar to OpenBSD is Slackware (witch I love) and in second
place debian.
This is my experiences running upgrades on OpenBSD.
PS: I noticed that I can found many resources (blog post, maling list
archives, reddit posts) that helped me to solve some problem
Best regards
