Today, i need to upgrade one of freebsd servers.
It run on freebsd 6.3 release version, so i want to upgrade it to stable version.
Here is my procedure for system upgrade

#vi /tmp/stable-supfile ---> modify supfile for stable

# The following line is for 6-stable. If you want 5-stable, 4-stable,
# 3-stable, or 2.2-stable, change to "RELENG_5", "RELENG_4", "RELENG_3",
# or "RELENG_2_2" respectively.
*default release=cvs tag=RELENG_6

#cvsup -g -L 2 /tmp/stable-supfile
#cd /usr/src
#make buildworld
#make buildkernel KERNCONF=GENERIC
#make installkernel KERNCONF=GENERIC
#make installworld
#mergemaster
#reboot
#uname -rs

FreeBSD 6.3-STABLE
