how to upgrade -stable to -r

[laszlo vagner]

i have a 15.0-stable install and am trying to find out how to upgrade to 15.1.

root@BigNAS:/etc/pkg # uname -a
FreeBSD BigNAS 15.0-STABLE FreeBSD 15.0-STABLE stable/15-n283007-e4f02a72f7f6 GENERIC amd64

my FreeBSD.conf file

# To disable a repository, instead of modifying or removing this file,
# create a /usr/local/etc/pkg/repos/FreeBSD.conf file, e.g.:
#
#   mkdir -p /usr/local/etc/pkg/repos
#   echo "FreeBSD-ports: { enabled: no }" > /usr/local/etc/pkg/repos/FreeBSD.conf
#   echo "FreeBSD-ports-kmods: { enabled: no }" >> /usr/local/etc/pkg/repos/FreeBSD.conf
#
# Note that the FreeBSD-base repository is disabled by default.
#

FreeBSD-ports: {
  url: "pkg+https://pkg.FreeBSD.org/${ABI}/latest",
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkg",
  enabled: yes
}
FreeBSD-ports-kmods: {
  url: "pkg+https://pkg.FreeBSD.org/${ABI}/kmods_latest_${VERSION_MINOR}",
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkg",
  enabled: yes
}
FreeBSD-base: {
  url: "pkg+https://pkg.FreeBSD.org/${ABI}/base_release_${VERSION_MINOR}",
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkgbase-${VERSION_MAJOR}",
  enabled: yes
}

i seen this on AI i believe but not working

To target FreeBSD 15.1 via pkgbase, create a temporary repository override directory or edit /usr/local/etc/pkg/repos/FreeBSD.conf. Set the FreeBSD-base URL to use the appropriate base_release_1 or version-specific endpoint and bypass strict OS version checks using the appropriate pkg command flags. [1, 2, 3]

Configuring a Temporary Override

Create a temporary directory: mkdir /tmp/upgrade-15.1
Write the override configuration: echo 'FreeBSD-base: { url: "pkg+https://pkg.freebsd.org/${ABI}/base_release_1" }' > /tmp/upgrade-15.1/upgrade.conf
Run the upgrade command pointing to your temporary repo dir and ignoring mismatches: pkg -o REPOS_DIR=/etc/pkg,/usr/local/etc/pkg/repos,/tmp/upgrade-15.1 -o IGNORE_OSVERSION=yes upgrade -r FreeBSD-base [1, 2]

anyone know the correct way to do this? its been a long time since i upgraded freebsd , it was way back when i did from source by cd /usr/src/sys/i386/conf and make , and make buildkernel KERNCONF=mykernelxxx

things change over time so im behind on the newer changes.

thanks
