I just read the friendly reminder
on https://www.freebsd.org/releases/15.0R/installation/ that
FreeBSD-EN-25:18.freebsd-update errata update should be followed.
That errata is, among other versions like stable/14, stable/13, avilable
for 13.5 releng and 14.2 releng:
https://www.freebsd.org/security/advisories/FreeBSD-EN-25:18.freebsd-update.asc
It says in its "Impact" section "When using freebsd-update(8) to upgrade a
system from FreeBSD 13.x or 14.x to FreeBSD 15.0..."
However, when looking at the installation instructions for 15.0 above,
these state "Systems running 14.3-RELEASE can upgrade as follows:"
This makes me wonder if 14.3 is the only version where upgrading to 15.0
via freebsd-upgrade is supported, or if, e.g., 14.2 or 13.5 would be valid
(and supported) starting points for the direct upgrade process to 15.0,
too.
Upgrading from any non-EoL release *should* work. But personally I would
upgrade to 14.3 first, simply because 14.3->15.0 has been tested far more.
