Let’s begin:

svn variants:

cd /usr/src
svn info | grep URL:

look at:
URL: svn://svn.freebsd.org/base/releng/12.1

switch to 12.3:

svnlite sw svn://svn.freebsd.org/base/releng/12.3

or

svnlite checkout svn://svn.freebsd.org/base/releng/12.3 /usr/src

But better use GIT because FreeBSD 13 avialable only at GIT

git variants:

git clone -depth 1 -b releng/12.3 --single-branch git://github.com/freebsd/freebsd.git /usr/src

or switch to another branch

git checkout -b releng/12.3

git pull

But I do not know how then pull and get src of 12.3 version like it normally do svn switch command

git pull says: Already up to date.

So the best way:

rm -r /usr/src/*

git clone -depth 1 -b releng/12.3 --single-branch git://github.com/freebsd/freebsd.git /usr/src

next steps:

make info:

-s Do not echo any commands as they are executed. Equivalent to specifying `@’ before each command line in the makefile.

-j max_jobs Specify the maximum number of jobs that make may have running at any one time.

some update info:

when mergemaster -p running be careful you need to add a new user ntpd

cd /usr/obj
rm -r /usr/obj/*
chflags -R noschg *
cd /usr/src
make -j4 -s buildworld
make -j4 -s buildkernel
mergemaster -p
make -s installkernel
make -s installworld
mergemaster -iUF
or:
make buildworld && make buildkernel && make installkernel && make installworld && mergemaster -iUF
next steps:
shutdown -r now
cd /usr/src
make check-old
yes|make delete-old
yes|make delete-old-libs

one more reboot:

shutdown -r now

and that’s all?

nope:

pkg info

pkg: Warning: Major OS version upgrade detected. Running “pkg bootstrap -f” recommended

pkg bootstrap -f

rebuild (reinstall) all ports

portmaster -af

better this variants to have some time for tea

-D no cleaning of distfiles

portmaster -afD

-d always clean distfiles

portmaster -afd
uname -mrs

FreeBSD 12.3-RELEASE-p5 amd64

P.S. while run mergemaster -p you need merge groups there are added two new groups.
